SupCom is beautiful, but only if you zoom in. The player spends almost all of the game at strategic zoom out, earning the nik "war of the dots". All you see usually is squares, triangles etc. Still, it's the best RTS I know. Amazing work in terms of tactics, viable strategy and depth.
It seems GPG was determined Demigod will be very different. And indeed, you can't miss the beauty of the game ( don't run it on weak graphics, it misses the whole point ). However, strategy suffers. The most obvious indicator is the almost complete absence of the scouting function. It's not important to find out what the other team is up to, because you already know it. All is left to do is gear up and plow ahead.
This is not necessarily a criticism. Not all games need to be about the same things, variety is a virtue. Just a matter of personal taste.
