The Touhou Odyssey:
Not going to discuss Plus Disk characters because of spoilers, you can poke me on IRC if you want to know about them.
Anyway, my personal insights on the game as a whole since I'm practically done with it (I'm not COMPLETE with it yet, I have to beat the other 30F boss and the True Big Bad)...
This game is a literal Disgaea past Floor... 25-ish? Random durability skyrockets, stat thresholds also skyrocket - I learned that level limit is the same as the 16bit integer limit, 65535. Someone I know cheated a level 3000~ish Marisa and ended up with well over 1.3m Magic, this is actually fairly scary. Tallychu mentioned in chat that stat growth is quadratic, which means this game IS CLEARLY NOT BALANCED and the programmers were on crack when they made it. Also I'm taking bets on how many times I kill the True Big Bad before I get bored of the game. Here's my opinions of some interesting Main Game characters:
Rinnosuke: This character is quite unique, decent ATK but somehow makes a far better twinked tank than even Tenshi, not to mention they have a panic button which pretty much nukes the TP in exchange for an insane buff. I ended up having to resort to this character later on when I found I didn't have enough bulky members on my team. Unfortunately, this person has the highest EXP requirement of ALL 40 characters in the entire game, which makes levelling the damn guy quite a hassle. The rewards are well worth it, though.
Okuu: Superior cat to Chen. Trades twinking capability and some speed with overall superior stats, a better skillset, and most importantly BETTER DURABILITY. Catwalk destroys random trash mobs silly, so she's up there with Ran and Marisa in terms of smashing up randoms. Man-eating Spirit has the benefit of doing dual damage, too, sadly it's SP eating, but it's nothing that SP twinking cannot solve. Overall a very solid character to use when you get her.
Suika: Smashes people to bits with physicals, but has worse physical durability than magic durability, as opposed to Yuugi who has amazing physical durability but gets destroyed by magic. I'm actually inclined towards Suika for the better oni, due to a little more balance. Not only is she faster, but has better growths in SP and Magic/Magical Defense. Also has a skill that restores status and buffs a fellow ally. Yeaaaah.
Mokou: Magical glass cannon what? Not as bad as Marisa, but still. She has some MASSIVE twink potential, and Woo has one of the scariest base mults for its cost I have ever seen (350%) not to mention it is a row based attack. Fujiyama Volcano is solid MT, unfortunately costing 118 MP. While it's nice that Woo is non-elemental, it can only go so far - Wind or Fire resistant enemies will laugh at her other solid magicks.
Kaguya: HILARIOUSLY bad HP growth, that I'm not even sure can be salvaged by twinkery (61 / ~7). Better nuker than Mokou, but far worse physical durability (higher MDef for what it's worth). Also has one of the most expensive ST buffs in the game, costing 132 MP. I actually have to credit Kaguya though for actually having a decent SP growth to support her insane costs...
Flandre: The epitome of physical glass cannon. 113 / 22 Physical Attack rating, also fire does not touch her. Even if it's magical, most of it is shaved off by her superior 342 Fire Resist. >_> Starbow Break is a solid 66 MP costing ST attack with a very scary mult given her stats, not to mention she is quite fast... I guess she's pretty one-dimensional? Actually, even Flandre's Magic attack rating isn't half-bad at 72 / 14... And this is great, considering Laevateinn and Forbidden Fruits run off BOTH her stats... Yeah. <3 She even has HP growth tied with Suika / Yuugi / others to offset her horrid defenses!
Reisen: Gonna have to agree with Tai on extremely MEH stats, but she DOES have a self-buff that boosts her stats by 40% (Medicine of Peerless Kingdoms). Not to mention her skills are scarily good for their MP cost (MT POIZN and 200% Mult off 48 MP? SIGN ME UP). Lunatic Red Eyes I suppose can rape randoms pretty easily if you MAG twink her and give her good MAG gear! I dunno. Still pretty interesting.
Nitori: Easily WORSE stats than Reisen in nearly every way possible (except Phys, which is STILL worse than Reisen's dependent offensive stat). Optical Camouflage is a very neat gimmick though. Would work much better if evade actually worked! But it doesn't so whatever. I used her to kill certain mobs down in certain annoying floors.
Suwawawako: Would actually be nice to have around if her durability were less horrendously mediocre. :[
