My game clock in Omega Quintet now reads somewhere in the region of 95 hours. I’m now about three-quarters of the way through my New Game Plus run and attempting to get the True Ending, and then there’s a bunch of post-game stuff, too, so that timer’s going to tick well over 100 by the time I’ve finished, I’m sure. This officially makes Omega Quintet certainly the Compile Heart game I’ve spent the longest on, and probably getting on for the overall RPG (Final Fantasy XIV excepted, of course) that I’ve spent the longest on. The previous record holders were Hyperdimension Neptunia Victory from Compile Heart, and I think I took slightly longer than the 100 hours I took for Victory over Xenoblade Chronicles on Wii — and didn’t see anywhere near everything.

Anyway. I don’t want to dwell on how long this game is — I could have been done long ago, since I’ve technically already “cleared” it once and I’m doing all of the optional side quests — but rather on something that I noticed as I was playing today: after nearly 100 hours, I’m still spotting new things about the mechanics and working out ways to leverage them to my advantage.

Compile Heart games are often quite mechanically interesting. The original Hyperdimension Neptunia, for example, featured a combat system in which I spent hours assembling combo attacks that would neatly chain into one another, swap out characters mid-combo and do all sorts of other cool things. The later Neptunia games took a different approach to battle, with freedom of movement, area-of-effect attacks and different types of strike. Hyperdevotion Noire is a solid strategy RPG with easy to understand but tricky to master mechanics involving elemental affinities, range, height and areas of effect. Moe Chronicle — my copy of which arrived today, hooray! — sees you equipping stereotypically moe traits onto a range of monster girls to give them various special abilities. And there are a few I’m still yet to play, too.

One thing that the Neptunia series in particular lacks a bit, though, is customisation. The characters aren’t completely fixed in their abilities — you have some flexibility in the combo attacks you can equip each character with, and it’s possible to customise the special attack combo-finishers they use, too — but so far as their main special abilities go, they’re fixed.

Enter Omega Quintet, then, which offers more customisation than I think I’ve ever seen in a Compile Heart game, with the possible exception of the original Neptunia. And it’s far, far slicker than that game — much as I love it, it was very, very flawed in many places.

The early part of the game sees you assembling the titular Quintet, and various mechanics are locked out until you’ve assembled them all and you’ve read all the tutorials (which are thankfully skippable, so you don’t need to read them again on a second playthrough). When the team is assembled and all the mechanics are in place, the default setup gives each of the five girls a different weapon and a basic few skills that they’ve already learned.

Skills fall into three broad categories: Elemental Skills (or E Skills) are magic-like abilities that either attack with elemental affinities or provide beneficial effects such as healing or buffing. Mic Skills — the weapons are known as “Mics”, because they’re idols, after all — are attacks that are tied to an individual weapon type, so the character must have the appropriate weapon equipped in order to use them. And Special Skills are character-specific attacks that require “Voltage” built up through performing well in combat to be able to pull off.

Of these abilities, only Special Skills are fixed on a per-character basis; everything else is fully customisable. The girls each clearly have a favoured weapon — the one they start with — but there’s nothing stopping you from levelling their proficiency in other weapons, too. In fact, it’s beneficial to do so, since levelling up a weapon proficiency provides you with additional “Disc Analysis” points besides those you already get from increasing the character’s overall level.

Disc Analysis is Omega Quintet’s main progression and customisation system. Each character has a large diamond-shaped grid with lots of nodes on it. Each node represents a new skill, an upgrade to an existing skill or a buff to the character such as additional E Skill slots or increased stat growth when levelling up. Spending the Disc Analysis points acquired through levelling and increasing in proficiency unlocks new abilities and opens up new nodes, since some nodes have prerequisites before you can use them or require you to “approach” them from a particular direction on the grid.

In my first playthrough, I wasn’t terribly careful with how I organised my characters’ development. I kept long-term goals in mind — “I want that ability that’s all the way over there” — and attempted to take the most direct routes across the grid to where I wanted to go, picking up any necessary prerequisites along the way. This mostly worked, but it left each character feeling fairly “generic”, since a lot of them had ended up learning the same or similar skills, and none of them were particularly playing to their strengths.

This second playthrough, I’ve been more focused, since I’m playing on the Advanced difficulty. (It hasn’t been too difficult yet, but that may be something to do with the fact I carried over my weapons and items from my first playthrough, making me a powerhouse in the early game) I’ve been specialising my characters and paying more attention to the “Chain Skill” system, which allows multiple characters to trigger more powerful special attacks if they perform the right skills in the right order using the “Harmonics” (simultaneous turn) system.

Kyouka, for example, has high Vitality — Vitality in this game is your speed stat, for some reason, rather than its more common usage as “ability to take punishment” — which means she usually acts first in a fight. This puts her in an ideal position to be a “buffer”, so I’ve given her all of the stat-boosting spells and, using her four actions per turn, she can increase any four of the party’s Song Power (physical attack), Stamina (physical defense), Knowledge (magical attack), Divinity (magical defense/healing power), Technique (accuracy) or Vitality (speed). Alternatively, she can use her spear skills to attack; she has a couple of useful area-of-effect attacks as well as one which draws enemies closer, helping to negate the damage penalty for attacking something at the “wrong” range for your weapon or ability.

Aria, meanwhile, has high Divinity, putting her in a good position to be a healer. So I’ve given her the healing spells. Her high Divinity also means that she can shrug off magical attacks quite easily — sometimes they even miss her altogether, and she has good resistance to status effects. When she’s not healing, her combat fan skills have some large area-of-effect attacks as well as two skills that steal items from enemies, making her very useful indeed for farming items.

Nene has the highest Knowledge in the party, making her the “mage”. Most of the other characters have fairly woeful Knowledge stats, making their E Skill attacks next to useless for anything other than the status effects or stat penalties most of them come with. Nene, however, probably does more damage with her E Skills than with her gun, so I’ve given her the most powerful, most costly area-of-effect offensive E Skill spells, making her a powerhouse for blowing things up. She’s also very useful for item farming, since her Special Skill comes with a “Rare Steal” effect attached, allowing you to acquire items that you can’t get otherwise. In the case of the powerful bosses in the Training Center optional dungeon, these rare items are extremely profitable, though you can seemingly only fight each of these bosses twice before they’re gone for good, so no endless farming!

Otoha and Kanadeko are more “average” characters, with their main strengths stat-wise being Song Power, Stamina and, in Kanadeko’s case, Vitality. This makes them solid physical attackers, and in Kanadeko’s case, her high Vitality means that she usually acts immediately after Kyouka, allowing for some quick hits before the enemy gets started on pummelling the party. The two of them are distinguished by their Mic Skills, however; Otoha has two large area-of-effect attacks and a huge area-of-effect Special Skill, while Kanadeko has some smaller area-of-effect attacks and a single-target Special Skill, but does considerably more overall damage and also has the ability to delay enemy turns with many of her skills.

Things get even more interesting when you throw the Chain Skills into the mix. Because Chain Skills necessitate each “step” being performed by a different character, this makes each individual character’s arsenal of E Skills important to consider to give access to the widest possible variety of Chain Skills at any given moment. But then you need to consider that character acting by themselves, too, since you can’t always guarantee you’ll be able to get the turn order to line up just the way you want it in order to pull one off.

Then you have the Neptunia-esque guard break system, whereby each enemy has a “magnetic field” surrounding them that weakens to varying degrees with each hit they take, and which replenishes fully when the enemy’s turn next rolls around. When the field is broken, not only does the enemy take more damage, but certain abilities — particularly Chain Skills and Special Skills — activate a special mode called Pursuit, which extends the usual animation for the skill and does additional hits, usually for quite a bit more damage. As such, it’s in your interest to try and batter the magnetic field down as efficiently as you can with low-cost skills, then unleash the powerful Chain Skills and Special Skills when the field is already broken, since Pursuit will only activate if the field is broken at the start of the move in question.

Sound complicated? It kind of is; the game does explain each of these individual elements to you on your first playthrough, but it doesn’t really tell you how to apply them to your advantage. That part is entirely up to you to figure out, and after nearly 100 hours I think I’ve pretty much cracked it. We’ll have to see if these tactics will take me safely to the end of the game and beyond, or whether I’ll have to have a strategic rethink at some point!

Anyway, I’ve been playing the damn thing all day so I’m going to bed now.
