I've been looking at it. Never really was a starcraft fan. I might grab once it price drops. Also wish it was offered digitally from steam too, as I basically buy all games from Steam now its nice to have 1 spot stop to redownload games etc.
Personally I've been playing (and loving) AI War Fleet Command, an indie RTS that is so in depth, and awesome. The AI is amazing, and makes the games a decent challenge. It also has the ability to do co-op campaigns multiplayer, with save ability so you can both come back later and continue(since games can last hours). I originally tried out the demo when it was on a discount deal on Steam, then bought it. Later bought the expansion pack too. The graphics arn't the most amazing, but its got a good artistic style that can play on a high range of computers (my netbook can play it, one advantage -- but i do have to turn off some of the prettier features). But I love long playtime RTS and Turn based strategy. Average time for a game is 5-6 hours or something I believe. It's crazy fun, and the AI still finds ways to surprise me and challenge while not feeling like I'm playing against a computer that just uses cheats in order to be "hard". They will attempt multi front attacks, scout, try sneaking past your front line and smash around your internal systems, etc. And the AI has a progress meter basically, where each time you do certain acts, kill certain units, build/own certain units the AI will progress and become harder. As it progresses it will send larger fleets, more often, and higher unit powers as it goes. It also starts defending a bit more intelligently making your attacks harder to complete. It's a fun game, highly recommended if you enjoy RTS to give the demo a shot

. I might get it pre price drop if a few of my friends end up buying it and want to play together.
