With all due respect to the OP, I must disagree:
I pre-ordered SupCom 2, and I have to say, I'm very pleased with it. Obviously it's not like SupCom 1 ... that would have disappointed me, because I didn't pay $45 to get more of a game I already own. It's not supposed to be an expansion, nor is it supposed to be SupCom version 2. I love Demigod and I love SupCom 1, and to me this new game is like a cross between those two. I launch SupCom 2 when I want to play a skirmish that is longer and more, um, futuristic than Demigod, but yet not quite as long as a SupCom 1 match, which usually takes me several hours.
As for the graphics, I think they're great. I am able to crank all the settings to max on my computer, and that looks great at 1920x1200 resolution. I can't see why the OP thinks they're so horrible. The best part for me is that the graphics are as good as SupCom 1 (IMO) but yet don't cause $2000 computers to lag, like SupCom 1 did. Zoom in on a teleporting unit in SupCom 2 ... I have never seen a visual effect in a game as cool and seamless as the effect shown when a unit teleports out.
I have to agree that the game doesn't have anything really groundbreaking to tout. But so what? Just because it's not groundbreaking, that doesn't mean it's a bad game. There are a huge volume of PC games out there, and not all of them can be groundbreaking. Not all of them can be thrilling, either. No, this game doesn't have anything completely brand new. But I still find it immensely enjoyable nonetheless.
I have to say, I think this game is suffering from the "iPad syndrome." In other words, false expectations. If you buy this game expecting it to be a new version of SupCom 1, yes, you will be disappointed. In fact, you will probably feel ripped off. Do NOT compare this game to SupCom 1, it's like comparing apples and oranges. SupCom 1 is an epic war RTS like Sins of a Solar Empire; SupCom 2 is a skirmishing RTS kinda like Demigod (which the OP obviously hates just as much).
If anyone is on the fence here, do yourself a favor and download the demo. See how you like the gameplay. If you can get your head around the fact that it is not a new version of, or replacement for, SupCom 1, you just might like it. If you don't, you're not out any money. I, for one, will continue to enjoy both SupCom 1 and SupCom2.
