I couldn't find any list that tried to be comprehensive, so here's my effort. Like real DLC-free, IAP-free, standalone games - most of them are short, some are good, some just weird, but in any case I find it interesting to experience those bite-sized, often innovative games. I've always been curious about the few, completely free games released on Steam.
