Well, after having played a few missions of the Supreme Commander campaign and played through the C&C 3 demo, I feel entitled to have a few opinions on this matter.
In short, Supreme Commander represents something new – namely, its enormous scale. C&C3 is more of the same – more polished, yes, and with excellent production values, but still just more of the same.
After having played SupCom, I felt incredibly constrained when playing C&C3 – I kept trying to zoom out to view more of the battlefield.
The cool FMV sequences and more entertaining story of C&C 3 could make me want to play it a bit more, but gameplay-wise, we’re talking Red Alert, and that’s what is sending me straight back to SupCom.
If there is a god of real time strategy games: Please combine the engine of Supreme Commander, the production values of C&C3 and the story of Starcraft.. please!
