I don't know if you guys catalog your PC games, but all of mine are listed at RFGeneration. I've been wanting to go through everything to see what's rare/valuable, or abandonware. I know that I've had to submit new entries for quite a few of them, and I'm the only one who owns a few of them on the site, so I'm sure I at least have some obscure stuff.

Anybody else have a link like mine? Might make it easier to see what's rare and what isn't.
