Kingdom Hearts for the motherfucking epic win. Hell, KH was my first PS2 game. Oh, also a fan of Tenchu: Stealth Assassins (although only the first 4. After that, they pissed me off).

I know what you mean, without mentioning Anime, it's a bitch. OH MY GOD!!! How the FUCK could I forget Avatar (and no, not the smurfs on steroids, The Legend of The Avatar... You know... Legend of Aang and Legend of Korra).
