Favorite series: Phoenix Wright (Gyakuten Saiban), Guilty Gear, Lunar, Castlevania (post-Symphony, except Harmony of Dissonance), Animal Crossing

Least Favorites

Least Favorite game: Probably Castlevania - Harmony of Dissonance, but (I don't know, I wouldn't keep playing something I didn't like)
Least Favorite character: Squall Leonheart (God, I hate this emo, closet-homo, mama's boy little prick)
Least Favorite male character: Squall Leonheart
Least Favorite female character: Fllay Alister (since Ion added Gundam SEED people) and (any of ditzy blonde female that does nothing but get captured or say stupid lines all game)
Least Favorite character from an rpg: Squall Leonheart
Least Favorite character from a fighter: (not sure just yet, I'll edit this later)

Least Favorite female villain: (not sure just yet, I'll edit this later)
Least Favorite genre: (anything they shove on X-Box and claim they're cool when it's the same kind of game repeated, doesn't mean I hate shooters), also Racing games (except Mario Kart)
Least Favorite soundtrack: Grand Theft Auto series (it's the same the normal radio, but worse, it's on repeat)
Least Favorite company: Sony
Least Favorite (current gen) system: (currently a tie) Playstation 3 and X-Box 360, neither have anything to really pull me to buying them, but X360 will be getting Resident Evil 5, so I can change my attitude about it to be higher then PS3.
Least Favorite (all Generations) system: Atari Jaguar or the Panasonic CD-I
Least Favorite series: probably Halo or Grand Theft Auto (mostly because I hate having to watch someone play either, BORING and Halo is a far cry from the glory of GoldenEye) (then again, I'd have to play that kind of game long enough to make me hate it, and I don't buy anything I won't like)

---------------------

To Ion: BTW-- Mai Shiranui is Fatal Fury, just King of Fighters is a crossover game for SNK, so most of their other fighting game characters are in it (Fatal Fury, Art of Fighting, recently Last Blade).
