I am looking for an online, open world, massive multiplayer game for the PC, preferably on Steam. The idea here is that I want something that my friends and I can log onto, meet up, team up, and do stuff, and then when we're done, be able to save and quit, so when get back on, we're where we left off both in physical location and progression in the game. Does this make sense? I want it so my friends and I to be able to form somewhat of a "permanent team". Certain games that caught my eye were Day Z, State of Decay, and Mount and Blade: Warband. Do any of these games fit the bill? Any other suggestions?
