Like tennis and other activities? Do you think...
A) You go to a tennis court or mini game location and it goes through a list of thousands of players to find you a match/opponent.
B) You go to a tennis court or mini game location but it requires that another player in the same world is with you also.
I really hope A but i think it's going to be like B. I prefer A as you're always going to get into a match or mini game, where as B it might be harder.
