If it makes you feel any better I just started playing No Man's Sky and compared to them Rohan gives you a veritable encyclopedia of help. NMS simply throws you in there and expects you to figure out what the keys do. It interesting if you are into explorer games with a pretty much infinite universe to check out. Though it is an MMO game, I doubt you will ever see another player in it even if there are over 200K players online at the same time.
