There's a lot of games out there that somehow get neglected in the general run of things. Sometimes, this is because of bad press or poor publicity, or just that the game itself wasn't very good. Sometimes, games don't always make it past the beta stage of development, leaving us with only incomplete demos or prototypes.
This site gathers together some of these lost games and digs around a bit, to see if there's anything interesting left. The pages may have details of content not seen in the final game (if there was one) and codes or hacks for rendering this content playable (if at all possible).
Update info can be found in the Tech Demo blog.
