Combined two games together

and make your GOTY.

Example:

SpinTires + My Summer Car = would be awesome

Mario Kart but with tracks that are from EACH characters original game. E.g. Kirby/Dreamland.

They’ve obviously done this before like with the Hyrule track in MK8 and also F-Zero & Animal Crossing tracks but I’d like to see it with each character.

At this point it should be known as “Nintendo Kart” anyway.

Reading back I haven’t combined two games together per say but it’s good enough. My mind can’t think right now. Lol

Metroid Prime and Overload/Descent. You play with Samus's ship and control it in 6DoF (six degrees of freedom), navigate in complex levels and find upgrades for it, scan areas and mine for info.

Gears of war dead space 1 make it more of a survival horror.

Resident Evil 2 with Dino Crisis. Zombies and raptors everywhere!

Watch_dogs and Assassin's Creed. We already know Abstergo exist in the same universe as Watch-dogs. What if Abstergo got a bigger role in an upcoming Watch_dogs game? What if you play a hacker with access to an Animus? Could be very cool. Or they could do some sort of multi-character switch like Rockstar did with GTA5. Possibilities are endless.

Final Fight with Street Fighter 2 characters. Funny thing is that Final Fight was originally gonna be a Street Fighter game. Imagine throwing fireballs and dragon punches in Final Fight. Love it.

Titanfall and Overwatch but with a single player campaign and D.va becomes a Titan pilot.

Total War style game but in Warcraft settings and lore. Like they did with Warhammer.

Nier Automata and Hitman where 2B is a stealthy assassin.

Nier Automata and Doom where 2B slices up demons from Hell.

The Division and Overwatch where Pharah and Mei are secretly Division agents.

Mechwarrior missions and tactics meets Titanfall speed.

I'd combine Doom and Timesplitters and create the ultimate FPS. Brutal, fast-paced combat, along with a strong single player campaign, good sense of humour, great multiplayer, and a ton of variety/customisation.

Hearts of Iron IV and Europa Universalis IV, that would be awsome...

Fifa and Micro Machines, although I think someone beat me to it!

Diablo 2 gameplay and loot and skill tree system.

But castlevania monsters.

A crossover between Ninja Gaiden and Nelo would be nice. I've heard a lot about how hard the latter is, so it'd be a perfect match. Coming supposedly to Xbox One soon (probably as an exclusive).

Monster Hunter and Devil May Cry

And because Monster Hunter already has Devil May Cry in many of them. Multi auto Game of the Years achieved (∩ڡ∩)

JACKPOT

Dragon ball and anthem. Uses dragon ball KI to kill the monsters in the trailer
