StonerMk2: Not sure if its been posted, but Direct2Drive has Kings Bounty The Legend for $2.50. Considerably cheaper then I've seen anywhere else, so if you've been holding out on the game for whatever reason, like i have, think this would be the time to jump on it. xD
They also have Company of Heroes: Opposing Fronts for $4.98. I have never played any of them so i honestly have no idea what the games are like.
Note: Might be region restricted.
The CoH games are pretty good. Best bet is to grab the Gold Edition of the original and Opposing Fronts, which adds a bunch of maps and doubles the # of factions you can play as to 4.
If you've played any of the Dawn of War games, they have similar mechanics in a WW2 setting (which makes sense, since Relic developed all of them). Pretty well polished at this point, lots of good maps to play on...I actually prefer skirmish play to the campaigns. And there are a ton of user made mods and maps available, too.
