Gameplay is really straightforward, you just have to travel across a desert, to the top of a mountain. You're totally on your own, unless you meet another traveller - the kicker is that all other players are all controlled by other players, but you have no idea who they are, and nor can you communicate with them. There are parts that are done by co-op, and working as a team with someone you just can't communicate with is very odd.
Stoners will cry at the beauty, or spend time trying to figure out why they can't talk to people, then give up and play with tin-foil instead.
