It's funny. Without Nintendo 75% of us wouldn't even PLAY videogames.
Just because a game is similar does not mean it's a rehash, guys.
I mean yeah, the third version of every new pokemon game ( r/b/Y, Y being the third version) is pretty much a rehash, but that doesn't mean every pokemon game is a rehash. Just look how much it changed from the fourth gen to the fifth!
Not to mention how much Mario Galaxy changed from Sunshine!
