The question isn't for me, but Smokin' Guns and CS2D are good indie games. The first it's based on Quake III and the second is an adaptation of Counter-Strike 1.6 but in 2D topdown multiplayer. Other games like Teeworlds, Tremulous and Momodora are good indies, and were more popular than Smokin' Guns, CS2D and Tremulous.
