Would it be possible to create a multiplayer war experience using several different games integrated into one gaming experience? In other words say you were a soldier in an FPS environment going through a particular mission and you needed air support. You could call another player who would be operating a flight simulator, and the pilot would be able to interact with the troops on the ground to give support where needed as an example.
The question essentially is what sort of design considerations would have to be taken into account to pull this one off? I understand this question is very broad. Basically I would like to know if you have 4 or 5 different games (FPS Shooter, Flight simulation, Tank simulation, Artillery simulation, Navy support, etc…), what would have to be done in order for each of these games talk to one another in UE4 for a smooth interactive experience?
