I couldnt get a game going with anyone. Lots of crashes.
But I did have a lot of fun playing with the AI.
My biggest problem right now, aside from the connection issues, is that playing against the AI (I tried both normal and hard), the cpu players were just not at all respectful of monitoring their life. Rarely did they retreat. They'd run in and fight me in front of my towers and creeps all by themselves until they died. And I think they also maxed out respawn time at their citidel, which only meant they fed me more often.
Pretty noobish, even for the Normal level.
But I suppose that if multiplayer gets fixed I won't need to worry about it
