Well, contest might be overstating it a bit.
In any case, Blitzkrieg is a game we advertised recently that I never took the opportunity to extol. I like it a lot, actually - it is a pleasure to see real-time strategy games incorporate elements like supply lines and realistic damage models. They have a demo actually, you don't need to take my word on it - or you could send a mail to blitzkrieg@penny-arcade.com and get lucky. I've got five of them here, and I already own it so you guys get them all.
