The game engine and complete open mountain experience really makes this game a lot of fun and endless in its activities. I only have a couple of small complaints that don't really take away from the fun of the game. The ability for users to filter/search/find the challenges/drop zones that you are looking for is really difficult; they need a better way of allowing users to find the challenges they are looking for rather than having to search all around the mountain range. The other issue that I have noticed is that there is a whole mountain range of areas for creating your own challenges, but only being able to have one challenge at a time is a bit limiting. Otherwise it is an awesome game and can't wait for the other sports and Alaska!
