Cool crossovers that you'd love to see

[Dark Soul # 7]

Heh, impossible idea but imagine if they could do a crossover game with Batman and Spider-man, and the Batman player has the mechanics from the Arkham games while the Spider-man player has the mechanics from the PS4 Spider-man game.

Clearing out waves of mooks together and then having a duo boss fight against like Killer Croc and Rhino would be ridiculously awesome.
