You could replay levels in Tomb raider, just like your doing for Destiny. The only real difference is that the people that made tomb raider didn't think replaying sections over and over would be something people would want to do so you get no "reward" for doing it. That being said I have spent a lot of time on this game too, but then I also spent a lot more (so far) time playing mercenaries and just cause. I just wish I would have gotten this game cheap like those because this to me it is not a AAA game, just a fun little time waster that I am reaching the end of (by end I mean I really can't go much further if I wanted to because they don't have matchmaking for raid, heroic strike or missions, and PvP is kind of unbalanced for high level people with no exotics.... and I have to do some crazy skill thing in pvp to even get an exotic... oh and I hate pvp in general and stink at it in every game so....whatcanyoudo.)
