Eh... it's more like it makes a ton of references to it. But seriously, go buy it. If you like it, you won't regret it. If you don't then you only wasted two and a half bucks.
It's a game. An awesome game that you should totally buy, especially since it's only $2.50 on the Steam store atm. I'm trying to think of words to describe it, but I've always been bad at describing things.
EDIT: Here, have a link to its Wikipedia article
I used the same two characters for every RP I did; I haven't had the chance to break out the really powerful ones. Although... I guess I could use Pokémon Champion Ian. I'd probably have to revamp him though, all of my characters were a bit messy back then.
Actually, it's not nearly as bad as I feared it'd be. It only took 20 minutes, and now, after I few hours, I'm feeling about 75%. It's nice to have it done.
