Decent. No expansion available other than prelude. Sometimes gets stuck and even restarting and resuming doesn't help. A specific state that causes it to hang maybe. Resuming takes a long time, feels like they just replay the player actions and evolve the state machine on the starting state when you do that. Weird but okay Edit February 2022: For some reason hard AI has started hoarding energy production without any clear reason. Makes the bot games too easy. Down to 1 star now. Please fix.
