The crazy group of sweedes that makes a lot of the games which have influenced us (HoI, EU2, etc.) is releasing their next game, Crusader Kings, next week.
I strongly recommend checking out Paradox's games. They're not always as polished as stuff that the huge companies can do, but they're very innovative and they push the envelope in a lot of ways that the huge companies are afraid of doing. They also have a hard time with their publishers -- especially their north American ones -- so show your support by pre-ordering CK directly from them, which helps their margins quite a lot:

(their web site is http://www.paradoxplaza.com)
Extra kudos to those of you who do buy CK, since I'm a history nerd, especially about that era.
