For me, ARK: Survival Evolved, aside from frennds. The games Expects the world from you if you play online, more so if you play pvp. However what keeps me going back is the game is more or less a breeding ground for primal reactions. Don't get me wrong Toxic players still sucks but when you take into account that all the work you built up over hours or days (if your in a tribe or not) can be lossed in less then 30 minutes. It does get a primal reaction out of players, along with the fact that the game has people who more or less could likely start doing well in politics (thanks to how pvp has changed over the years). Some times the death of a whole sever can be stopped just buy coming to an agreemnt.
It may sound dumb but I think that's the core strength of that game.
