Well, I tried the demo and it was quite...bad after having played Supreme Commander.
Somehow that old gameplay with limited ressources, weird units, IMO bad animations etc doesn't cut it anymore. And that small skirmish map didn't really help. The whole thing just feels like playing in a sandbox on low difficulty and on medium it starts being stressful and no fun anymore.
Well, it's fast gameplay and I'm a slow person, so maybe it's just the combination.
I agree with you completely.

There where nod turrets popping up in my base. I thought the AI was then going to get an uber l33t bonus, and unleash a load of uber l33t l33ters to unl33t my base uber base.
