Don't have a Top 10, just a toobular 7

Platformer - (Mario, Mega Man)
Action/Adventure - (Zelda, Metroid)
Survival Horror - (Resident Evil)
Puzzle/Adventure - (Zack & Wiki)
First Person Adventure - (Metroid Prime)
Arcade - (Donkey Kong, Space Harrier)
Fighter - (Super Smash Bros. & Street fighter)

I absolutely love being confined to small areas in a game while having to solve puzzles, find keys, save ammo like they're diamonds,
doing lots of back tracking, battleing the undead-...Yeah, kind of sounds like the traditional RE series.

There's nothing more satisfying than FINALLY finding a key later on in the game that unlocks that ruby diamond red door during one of the beginning portions of the game you're playing hehe.

10. Proper quality First person shooters (DOOM, Half-Life)
