Like? Hunt animals and climb radio towers? I'm really asking, because from what I saw from reviews didn't see anything impressive, just a blown out of proportion bubble. So far it didn't impress me to pick it up and try. Maybe some day with big hangover and nothing to do...
Just get the game you'll understand and you'll love it. Its just a good mix of different game styles. The story is awesome as well as the map being fun to explore.
