I would like to add Payback 2, originally (since 1999) a nice and technically impressive GTA 1/2 clone, now it grew past just that concept and includes a bunch of game modes and nice multiplayer
I usually just lurk, but it still feels different here. As other people point out, it's similar to the internet's old days, and although I never got to experience that, I think I feel the same way. It's more free, less crowdy and noisy.
I still find myself needing Reddit though because of the more niche communities and content.
