The old old old original Legend of Zelda. All the new stuff and 3d games are childish and cartoony. The first one is really movie capable.
I also really want to see a more mature pokemon movie, where pokemon die instead of fainting
Mass Effect because it already has the potential of becoming one. And it would definitely have Seth Green in it. Also I would love to see Duke Nukem. Although this era of actors don't have those good ole' 80s actors that were big and fit the role... Arnold.
