PokéMon

I am a piece of shit and I've played through all 5 generations, and now I'm waiting for the sixth... It's stronger than me; maybe some of the little monsters are crap (but even in the first ones there were some horrible or unoriginal things, indeed the first generation was practically just amorphous animals, not monsters at all), but it's always so much fun. Plus, it's a game with incredibly complicated mechanics; I enjoy it more now (knowing what I'm doing) than when I was a kid.
