As with any truly good games, there's an entire subculture revolving around SC2. Its surprising to find a game that's 8 years old and still has a small, but fervent fan base. There's even a clone called TimeWarp that's being very actively developed, and within the last month or so started supporting multiplayer over TCP/IP; a feature that has never been seen in any Star Control game. There's even an IRC channel on EFNet (#starcontrol) that actually does occasionally talk about Star Control (though that's largely due to the development of TimeWarp.

You should be able to find links to anything and everything that's significant in the Star Control community by going to the Pages of Now and Forever at http://www.star-control.org/.
