So besides steam, whats the next major game distribution site you use? I'm currently using itch.io, with is working out pretty well for me.

GOG is the only alternative I know of, but I don't personally use it. Steam works, and it has all the games I want to play.

Would appreciate if one of the lmod/smods put this into rapid threads, still looking for some alternatives.

I've heard some good stuff about Desura. Haven't used it yet, so I cant evaluate, but you can check it out here

think it may be more focused on indie games, and it is a bit recent (2010)
