I got the game for $30 on Amazon. I was amazed at how much it did behind the scenes for installation. It took over an hour to install everything!  Started with Steam, I had no account for it, then it added the updates, lastly it hooked me into G4WL which I've not used before (only used XBL).
 
My PC isn't the best for games, but it's still playable. I was afraid I'd get errors or crashes but it was all seemless despite all this crap it installed on my box.  Well I did get an error the first time installing it, my CPU overheated, but that's not really the game's fault & appears to be an odd glitch with my PC that occurs every now & then.
 
Anyway time to check out some of the achievements & start playing this beast. I heard some complaints about the campaign not being an RTS, but I prefer action RPG anyway, so that's fine with me.

Ok, I hope you enjoy it.

Online is more so traditional RTS, though no base building really. Main game is more of a squad like action rpg. I think the game is really great, and hopefully you enjoy it.
