When I go to a site like 1337x or tgx, they never have smaller games, and if they do, they have no seeders.
Just make sure you buy the game if you really like it. Indie devs need the finances. Also, Steam apparently has 90 day trials coming up for games that allow it. Not many atm but something to keep an eye on.
Mega Thread > Games > number one in the list
You need to go to private communities like GGn
better off with the CSrin forums for smaller indie games IMO
Check out GazelleGamesNetwork. That seems to be the best games tracker as far as I can tell.
RetroWith.in came from the ashes of UndergroundGamer. As the name implies, they are limited to games before a certain date.
PixelCove is a good tracker for games also.
