Topic: What crossover games would you like to see next?

Mario + Rabbids by Ubisoft / Nintendo is going to be released in a few days and so it is time to think about further crossover games that could shock and surprise us. So what crossover games would you like to see next?

Luigi + BioShock by 2K / Nintendo?
Star Fox + Monster Hunter by Capcom / Nintendo?
Metroid + Dead Space by EA / Nintendo?
Mario + Mickey by Disney / Nintendo?

How about a Pokémon X Monster Hunter game. Hunting and killing Pokémon, though, could be a bit .... gruesome and I doubt TPC is gonna let that happen.

I always wanted to see a Mario + Sonic game outside of the Olympic Games, where Mario platforms through Sonic's world and Sonic runs through the Mushroom Kingdom. Always envisioned with a Sonic Colors/Mario Galaxy type of gameplay where the platforming is done in 3D locations but the goal is still to reach the end of the level. But I've heard that SEGA proposed the idea but Miyamoto and/or Nintendo shut the idea down.

What about a Metroid/Bayonetta crossover?
I would be down for it.
Or maybe a Metroid/X-Com game. RTS gameplay with Samus.
All the possibilities.

Bayonetta + Devil May Cry.
Actually, there's probably (almost certainly) fan-fiction and/or Rule 34 material on that already ...
::heads off to Google::

Steep + Ice Climbers !

Can we have an ACTUAL Mario and Sonic spinoff instead of just a sports spinoff?

Kingdom Hearts, but then replace Disney with Nintendo. So SE and Nintendo basically.

Warioland + Castlevania would be fun.

Kirby X Pacman: The Hunger Games

Mario Kart + Grand Theft Auto

C'mon, that would be awesome!

People are saying Metroid or Monster Hunter, but no-one is saying Metroid X Monster Hunter. Hunt Aliens, use pieces to upgrade Samus' beam weapon and armour. Great fun.

Lego + JoJo's Bizarre Adventures!

With the option to create and customize both your stand user and your stand

They had colaborated (SquareEnix and Nintendo) on Mario Sports Mix Wii.

Animal Crossing x Animal Boxing NDS.
Cute Boxing games features Human vs Animal, just like Animal Boxing NDS.

Animal Crossing meets My Sims. Colaboration of Animal cuteness and Chibi My Sims characters in The Sims style. Imagine you can create your own Town with heart desire of Town design, house design, the Animal Villagers or Townie Sims who will stay at your town, Mini games, Event Festival, etc.

Doom & Rabbids - Hell Battle

Also Sonic + Nights. A normal 2D Sonic game for the main stages and Nights gameplay for bonus stages

Mario Kingdom + Civilization

Star Fox x Metroid (x F-Zero)

With this crossover Nintendo could push two or even three IPs at once and such a game - obviously taking place in a futuristic world - could be REAL fun.

Not exactly a crossover but I would like minigames in Animal crossing, something like the minigames in No more heroes 2.
You could use those minigames to make money. There could be for example a platformer game where you collect coins, a game where you kill bugs (I hate bugs, killing them would be much better than collecting them!) and a racing game where you have to deliver goodies for Tom Nook.
It would be great imho
