Do you want another game of zombies?
Metroid X Megaman
We see "new IP" all the time in the form of fresh skins over copycat games - like the army of military themed first person shooters. People seem easily tricked by a coat of paint.
new gameplay is the only meaningful "new IP" that anyone who cares about games should want.
Nintendo is talented at creating characters and worlds because they put a lot of care and crafting into them. This makes them conservative about creating "new IP" as people perceive it, willy-nilly. They seem like they don't want to waste shots at new properties by tossing out something unoriginal and half-baked.
They do need to create new characters and worlds, because they're very good at it. But never mistake that for not making new "gameplay", which Nintendo does all the time. If anything, they are entirely predicated on making new ideas and gameplay.
But then people just call those "gimmicks"...
I don't see you posting in The Wonferful 101 thread. Almost nobody who usually complains about Nintendo's reuses of their franchises did actually.
And even then, better overall game trumps "new IP". I guess people just like to tout it because it's the only thing they can proclaim.
Anyway we're getting off thread.
A Mario x Sonic game. Mostly because I don't feel Sega has ever used Sonic properly and I think Nintendo could really make the gameplay amazing.
Better yet, leave Mario out of it. I just want a Nintendo developed Sonic.
Considering Nintendo struggles with third parties, and time requested for HD development, I think that this could be an interesting way of pushing more games on the market for the Wii U.
Of couse, those should be smart partnership, especially in terms of genre (not as an action for Metroid)
That said, I honestly don't know which other partnerships I would like to see.
Fantasy Zone x Star Fox
Cave X Nintendo would make me excited too but it'll never happen. I'd like a dedicated Nintendo bullethell and crossover cast starring in it would thrill me.
I haven't really got anything special though to add. I just woke up.
FUCK I just thought of that as I scrolled down! XD
Monster Hunter X Pokemon
That'd something I'd like to see!
But yeah. With Pokemon Conquest and now this, I think it's a sure bet we'll see more.
Pokemon and Tales kinda sounds uber awesome, Pokemon in Vesperia graphics? Yes please.
Zelda and Soul Calibur? OH WAIT!
Game Freak is still 2nd party correct? Even though, Nintendo should be able to get them to do this.
Finally fusing Pokemon and fighting alongside them :)
