For my own personal nominations, I'm going to let you guys nominate the serious contenders, and stick to some fringe favorites of mine. I'm betting this won't get support votes from anyone, but that doesn't stop me from liking it. It's an old PC shareware title, if you're not familiar. Released in like '95, and rereleased by another company in '00 under the name Tyrian 2000.
