I was wondering. Most multiplayer gameplay always favored by Wi-fi during team-up or to compete each other. I know that when in comes in huge groups (say 100 to 500 players or more online) in online games whether it's cooperation or battle, most players relying on Wi-fi to play in very huge group.
What if some persons wants to play in small groups and can be played offline (like in racing games or fighting games for example) using smartphones via bluetooth? The question is that are there most game apps for multiplayer gameplay still favored or popular of using bluetooth when playing in a very few no. of players (let's say only two players) on a certain game?
Also, is it possible to create a game app for iPhone or any smartphones that run on Android that features bluetooth for multiplayer via Unity 3D game development software?
