I haven't really blogged about this much on this particular site, but I figured it's time to sit down and talk about it as it's something that I've found consistently interesting for quite a few years now.

The subject is virtual worlds – online spaces where tens, hundreds, thousands of people can log in and join a virtual community for one reason or another… it may be purely to socialise, it may be to battle monsters, it may be to have fun, it may even be to have sex. And I'm not talking about community or social networking websites here, as those are a different beast entirely. No, I'm talking about actual virtual worlds, where you can wander around as an avatar, explore the world, meet other people and interact with them in any of the ways described above.

There's literally hundreds of virtual worlds available for people to use nowadays, of many types – some are more "gamey", others are more "social", others still are focused on the less salubrious side of online interactions. Today I want to focus particularly on the virtual world of Second Life and its appeal to me, despite its many, many flaws.

I remember first hearing about Second Life while I was big into The Sims. My whole flat at university became obsessed with The Sims shortly after I built our first house, made virtual representations of all six of us in the flat, then realised that we didn't have enough money to buy beds to begin with, so the whole "family" slept in recliners. Over the years – yes, I was that guy – I bought most of the expansions and later moved on to The Sims 2.

I was, like many other fans of the series, extremely excited at the prospect of The Sims Online, offering the opportunity to have the same kind of fun, but with other people involved. It never made it over here to the UK – at least, not in any prominent way – so I never got the opportunity to try it. I forget exactly how I came across Second Life as a result of this, but it was something I stumbled across without hearing anything about it beforehand, and I thought that the concept sounded rather like The Sims Online, with players being able to design their own virtual person and "live" in a virtual world. As it happens, it has very little to do with The Sims Online, but I wasn't to know that at the time.

For the uninitiated, Second Life is an ambitious virtual world project by Linden Lab, offering "players" (and I use the term loosely, as it's really not a "game" as such… unless you choose to make it as such, which we'll discuss later) the opportunity to enter a world that is almost entirely user-generated. Buildings, textures, landmasses, interface features, animations, body parts, clothing – everything is created by the residents of the virtual world, and this is the thing that initially fascinated me. I couldn't comprehend the idea of being able to log into something where the content was so fluid, where there wasn't a static virtual world that was always the same every time you logged in, with monsters in the same place, prime "camping spots" and so on. So I signed up and signed in, not really knowing what to expect.

Second Life is a peculiar experience the first time you log in, especially if you're more used to aforementioned online games with static content, such as World of Warcraft. You quickly become used to the concept of "rezzing", which is the process whereby you enter a new location and you can see things downloading and appearing around you. This is disconcerting the first time it happens (and more than a little irritating if you find yourself stuck against a wall which hasn't appeared yet) but, like many things in the world, you become used to it the more it happens. Similarly, you become used to the fact that other residents' avatars also go through this rezzing process in front of you, so it's entirely possible that someone could appear in front of you with no hair and no face until the textures and shapes have downloaded. Rezzing accidents are the subject of many a good laugh amongst SL residents, but they are accepted as part and parcel of life in the virtual world. People more used to traditional MMOs will likely find it a complete turn-off though – at least until they accustom themselves to it.

Upon arrival in SL, the question on many residents' lips is "what on earth am I supposed to be doing?" And the answer is not simple. Explore, interact, build things, take photographs, join groups, play games, look at art, shop, fuck, roleplay, pretend to be a vampire… the list goes on for a mile, and all of these interactions are built using the basic engine of the Linden Lab-developed software, with extensions built, designed and scripted by residents of the world, just like everything else. People make in-world money either by paying out of their own pocket to buy "currency" – or by working a job, just like real life (albeit with MUCH better hours). It's always interesting to hear how seriously people take their SL jobs, whether they're a DJ in a club streaming their music through something like ShoutCast, a live musician, a virtual performer, a dancer, a greeter, a builder, an estate agent, a facility manger, a prostitute, a Game Master for roleplaying areas – again, the list of things goes on, and people have the opportunity to completely subsidise their virtual existence through virtual hard graft if they so desire.

Another thing that is almost immediately noticeable about SL is the sheer diversity of the avatars present. And we're not talking a set choice of races here, with arbitrary "body size" sliders. We're talking complete customisation. We're talking this situation here:

This wasn't anything particularly special happening – it was a discussion group where we sat down and had a civilised chat about a set topic. Like a real-world discussion group in fact.

And that's the thing with Second Life. It has this immensely odd (yet perfectly natural-feeling once you've been there a while) ability to combine the mundane and the absurd. Everyone is distinctive in Second Life – because you're not limited to hard-coded appearance options, you can be whoever you want to be. You don't even have to be human. I picked up an awesome Pac-Man avatar the other day that allows you to spawn dots and ghosts and turn any place you go into a game of 3D Pac-Man.

In fact, the question of not being human is one of the more interesting sides to Second Life that I haven't explored yet. It also happens to be the side that there's a lot of sordid assumptions about, particularly around the "furry" avatars. Yes, there are people who choose to represent themselves as furry animals and then have simulated sex whilst masturbating furiously at the sight of their interlocked pixels. But equally there are people who choose to represent themselves as furry animals just because they like them. On one memorable occasion I was spending some time at a hangout with my earliest friends in SL (who are still good personal friends to this day, I might add) and I was introduced to an immensely clever man from a university who was working on lots of exciting things to do with AI. My friend Lyndy, who introduced me, assumed that because I "knew about computers" I'd be able to chat to this guy no problem. However, he was explaining concepts that were way over my head… but they were interesting to hear. The really peculiar thing, though, was that he was dressed as a fox. Not a foxy lady, no, an actual fox. In a waistcoat. If anyone remembers a really old DOS point-and-click adventure called Inherit the Earth… the main character from that? Fox-in-a-waistcoat called Rif? That's about it.

Why do I remember that? I never even played it.

Second Life is flawed in many ways. I've talked about this many a time with Jennatar, and she suggested the notion that virtual worlds are a much younger technology than the Internet. Currently with virtual worlds, she says, we're at a similar sort of stage to the Internet was in in the early 90s in that there's a lot of stuff out there to explore, but navigation, user interfaces, efficiency and practicality haven't quite reached the level of stability you'd need to be completely "mainstream". This means that titles like Second Life are, at least for now, going to be "niche" interests. However, interestingly, the "niche" for Second Life perhaps isn't what you'd expect – an oft-quoted "statistic" is that of the many residents of the world, a significant majority of them are female and over 30. This is certainly true amongst my circle of online friends – I think there's one guy and about thirty gals on my friends list. This is also backed up by the fact that the "retail" sector in the world is very much female-dominated, with vast business empires and shopping malls devoted to female clothing, hair, animations and the like, with male products often relegated to the virtual equivalent of a dusty old cellar. One may argue that this may lead to a lot of males representing them as females, and of course this goes on – given the opportunity to live out a fantasy life, I'm sure there's plenty of men out there who wonder what it would be like to be a woman – and a hot one at that (no-one is ugly in SL unless you make a specific effort to do so!) – and give it a try.

There's a kind of implicit understanding amongst residents though – don't ask, don't tell. If someone doesn't want their "first life" brought into it, then you don't ask. If it's a female on the screen, then as far as you're concerned, it's a female you're dealing with. I actually don't have a problem with this. Perhaps it's because I'm not spending my time going around having sex with these people, but it certainly doesn't bother me – if they choose to represent themselves in that way, for whatever reason that might be, then that's their business.

Despite its many flaws and its perceived "niche" interest, I have a lot of time for Second Life. It's an experience that is very much made by the people you interact with. Without people to meet, talk to and interact with you're relying on stumbling across interesting content solo – and while there is plenty of interesting stuff to do by yourself, it's always better to share with other people. Much like real life, in fact.

I'll certainly be very interested to see how virtual worlds develop over the years. Will Second Life remain in its pioneering position of almost entirely user-generated content? Will it be overtaken by something else? Who knows. I do know that I have made some genuinely close friends in its strange world, many of whom I am unlikely to ever meet face-to-face. And I'm fine with that. By having their "virtual" face in front of me on the screen – even if it's nothing like their real-life face – I still feel like I "know" them better than people I interact with on the Internet in less direct ways. Perhaps "know" is the wrong word – it's difficult to describe, but knowing someone's avatar feels a lot more "physical" (for want of a better word) somehow than a username on a page of text.

It's not an experience for everyone by any means. It would bore the pants off someone expecting to play an exciting game, because it's not a game. But as a means for virtual social interaction, it's an interesting experiment… one that still has a long way to go, but also has an incredible amount of potential.

I blog about my experiences in the world in more detail here. I post my photos from the world here. Feel free to check them out if you're the slightest bit interested.
