Jester and Diaglo mentioned 2 of my favorite tabletop games, so I have to speak up.
Roborally- Excellent game, now out of print..BUT there are rumors of a new edition in the works! Keep your eyes open, Jester!
Chainmail- I love this game...I invested many hundreds of $$$ in it, even as it was being cancelled (WOTC Schmucks). I got some killer deals on it, too, as much as 80% on some minis. Bought Dwarven Forge stuff to design great setups. Then my game group expected me to do 100% of all setup, including designing and allocating warbands. (Gamer Schmucks.) I can't get into the plastic minis of D&D Miniatures game, even if its substantially the same game as Chainmail. However, Rackham (Non-Schmucks) has Confrontation- which is essentially a metric version of Chainmail- and the minis are EXCELLENT. Recently, Rackham has released an English-language version of the game, so you don't have to convert everything from metric/French (like I was doing).
