Half-Life 2/Source SDK still owns them all. So much variety, so many different games. From Empires to Underhill a whole world was waiting. Unfortunately the engine got a bit old, so I'm not sure what can and will replace it. Other games have lots of mods, but a lot of Source Mods actually went on to become retail games (e.g. Insurgency, Natural Selection); I like that!
