The "Mario Galaxy 3" shit needs to stop. Galaxy 2 was good, but completely unnecessary, and Galaxy 1 was already perfect. If they make a second 3D Mario for Wii U (which I assume they likely will), then it shouldn't be another space/gravity physics adventure, but something totally different from Galaxy OR 3D World. God forbid they maybe finally take it back to the Mushroom Kingdom........
Anyway:
PS4: Naughty Dog needs to hit the breaks on the "playable movie" stuff, go back, and make a new, GOOD Jak & Daxter game, and cut the bullshit from Jak 2 and 3, make the game play more like the original, make Jak mute like he's supposed to be, knock off the GTA ripoff gameplay, and get back to basics.
Wii U: The obvious answer is Star Fox. A TRUE, honest to god, so-good-you-die-from-playing-it Star Fox 64 sequel. Again, forget ALL the stupid bullshit that was tried with Adventures, Assault and Command, make it play like STAR FOX. I would honestly prefer Nintendo to have the same basic in-house team who handled 64 to do it, but I really don't care who makes it so long as A) it isn't Namco, B) it isn't Team Ninja, C) it STAYS in vehicles the whole damn game, and D) it's fucking AMAZING.
