It would be great to have the option to use multiple controllers simultaneously for more simple, single view games (e.g puzzles / block building / drawing etc). I understand that there are probably some software workarounds to control multiple mice on a single screen, but having a simple in game option to use multiple controllers simultaneously would be great for fun casual party / hang out games.
I'm hoping to get some friends & family into TTS when they visit for the holidays this year, being able to use a local co op feature like this would be a blast !
