Well,since I am amused by the drop system in CSGO. But what about L4D3? Will there be mods to subscribe as L4D2 workshop or just drop system and marketing? Though I do bet some of these L4D3,Portal 3,(non-included TF3),HL3 MAY have drop systems...except TF3 I just made it up... Thus would be interesting...If of course Valve will add anyway one of these games in the future.
