Likes : Uncharted 1&2, live action Transformers, good anime (Akira, Ninja Scroll, Cowboy Bebop, Miyazaki for example), Street Fighter II/Alpha3/IV (particularly Chun Li & Rose), big juicy bloody steak, DC comics (Green Lantern, Batman, Superman etc), Doctor Who from any era, Firefly/Serenity, Iji, LittleBigPlanet, ThunderCats, The Warriors (game & movie), Turrican II on Amiga, werewolves, devil women, Super Metroid, Castlevania - Symphony of the Night, Robin of Sherwood, proper retro looking games that bring back happy childhood memories of playing on the Amstrad CPC, Amiga or even NES, banoffee pie.
Dislikes : Nearly all FPS/RTS/RPG games, 2D games that use mouse aiming, post-SNES Nintendo, Sonic the Hedgehog, Gordon Freeman, Lara Croft, anything too kiddy especially japanese, crap anime (Dragonball Z, Pokemon and such), trendy vampires, zombies (overused), Harry Potter, Lord of the Rings (actually most fantasy magic stuff), anything by Pixar 'cept Toy Story, carrots.
there ya go. Enough to choose from and enough to avoid too I reckon.
