The professional reviews of this game don't do it justice. It may not be an immersive game experience, but it IS fun!
I am stuck on the final boss ... I may never beat him - he is tough. But the journey to get to that point was well worth it. There are a few problems as in most games. The map doesn't seem to show your current position, unless I am missing something. It is possible to get stuck at the final boss not having upgraded your equipment enough. You cannot back out of that confrontation as you can all of the others.
There isn't one specific thing I can say about this game that makes it fun. It is just the game as a whole ... such as scalping. It serves no useful purpose, but it is funny to hear the victim complaining that you are taking his hair "aww not my hair .. .blah blah".
Pick this up - it is great!
