It was hard not to give this game a great score, because there will be some people who will love it. Unfortunately, while the world is huge, and the antics of your Neanderthal are hilarious, there really isn't a major goal to the game. The only way you truly beat Tail of the Sun is by building a tower of mammoth tusks so that you can reach the sun. This is accomplished by going up North, killing mammoths, returning home, and repeating the process. What really makes the game a blast is just roaming all over the expansive world, finding new landmarks, and killing critters for food. It sounds silly, but it's a refreshing change from games that push you along to an ultimate goal that you may or may not care about. Rent this game and check it out. It's cool.
