There didn't seem to be a way of removing armies on the player selection screen.... unless i missed something (so sleepy......) how do i remove some of the ai opponents for just a 1v1. Also, it seems like the ai just builds some defense and flys units only around its base? If so i guess not much to worry about lol almost-sandbox is fine enough right now!
This alpha really isn't meant for you to play solo games against AI. I don't expect the real AI to be implemented until late beta or release honestly.
