Finely tuned game with extremely addictive game play.
1. The world is huge and there are many places to explore
2. I didn't have to really do anything within a certain time frame. (There were timed tasks but I could start and stop them whenever I wanted.)
3. The controls were extremely easy to use.
4. The character acting and storyline was interesting.
5. The graphics were excellent (There are places where you have to climb and jump off of. The graphics were so good at some of these places that my stomach started feeling funny as Altair climbed.)
6. Because of the science fiction aspect to the game. There is a lot that can be done with the story.
7. The fighting cut scenes were really innovative.
There isn't much I would change about the game.
