I suggest we make a mode that won't take time to implement and it will be easy to make and besides that will help with the balance problems or with the balance testings.
It goes like this:
!setoptions zerokmode=limited resources
In this mode you just have 2000, 3000, 1000, 500 or how much metal and energy you chose before starting the game. After you chose the numbers you can select what units you want from all factories and then start the battle.
Buildings, factories and others will be blocked, and only the starting selected units will appear on the battlefield near your commander.
I am very curious what the pro 1 vs 1 players will chose as units when they use this mode.
