Derek Smart still releases games, he recently started up some new episodic content, said that if you played his game and didn't like it, he'd personally refund the money.
His forums are so funny. Some guy was talking about how this new game had strange graphic effects and looked ugly, and Smart came off and called him a "fool", saying that it was intentional and gave a bunch of techno-babble about why that was.
As much shit as Smart gets, you gotta admire the guy. His games are extremely deep and have a ton of potential, and he's more or less doing everything on his own. If he had a competent team behind him, he could probably make one of the greatest games, but his ego won't let anyone else share in his glory. The worst part is the damn techno-jargon that he throws around in his games. The manual is the size of a phonebook, but the game is impossible to play unless you read and memorize everything. Hundreds of acronyms, technical terms, buttons on a spacecraft, etc. The learning curve is absurd.
