So you're playing a map, and you win/lose and you want a rematch. Problem is, you have to go back and recreate the game and make sure that your friend/stranger joins and restart the entire game. With this map, all you have to do is type "Replay?" and it sends it to your opponent. If your opponent agrees, the game "resets" (Minerals, gas, destructables,all units killed) and you can choose whatever race you want to replay with. Simplifies the process of getting back into the game. Best part is, the triggers used in this map can be copied and pasted onto other 1v1 maps (Larger players I haven't tested yet).
