I got the game last friday - and have just finished both campaigns. the DRM is minimal (just always there) and I only had 1 interruption to my gameplay.
Sadly, the game just doesn't measure up to the hype surrounding it. While I look forward to the multiplayer 5v5 action, it was hardly the game I was hoping for.
That said, I will say that the strategy that will be needed for multiplayer will be a refreshing change from the spamming most CNC players prefer...
so roll-on cnc5 - maybe we will see the end of the saga...
