Bought this game on CDkeys after upgrading my i5-2500 and gtx970 to a 7700k and 1080Ti and loved this game. Sure , some will complain that it is too simple or too short or too boring, but for the $10 the game cost, compared to what you'll see when you play through it. It's definitely worth the price of a ticket to the movies (with some replayability).
Haven't tried multiplayer, but it definitely justified the graphics card - Crytek games are always stunners.
