Which game builder can add multiplayer to a game?
We need a game designer that can add multiplayer to the game, let's say that 1000 people play the same game in different modes at the same time (well, I think everyone understands that there is multiplayer)

Answer 1

All popular game engines can play multiplayer, even such a miracle as GameMaker.
