I would love to see my lil' ol' Mario jumping his way into some sweet achievements on my 360, but alas, he is a Nintendo baby and the world will end if Nintendo lets him go multi-platform.
I really don't understand all of the complaining that goes on when a game goes to other consoles. I choose to play it on the console I want, and could care less about another person's choice of consoles.
I will probably own a PS3 by the end of the year just because I really want to play the new Ratchet & Clank game with my son, so I really can't say I am loyal to any game system.
I just buy them all eventually! Woohoo, video games rule, even at 33 years old.
