My boyfriend bought me this game for Christmas and we've been playing it with his friend. If people are looking for a well rounded survivor game that doesn't just consist of logging in and getting shot by another player, Ark is a good one. So far the community on my server is really cool. We do have players who try to kill people on sight but it's pretty easy to get a witchhunt out on them.
And dinosaurs! It's like being in Jurassic Park.
