Tony Hawk's Underground is very different from the previous games in its series. The story mode is a wonderful addition and is the best new feature. You play as yourself and you work your way up to becoming a pro. There are goals which involve driving as well as skating. It takes 10 to 15 hours to beat it, which is a proper length for this type of game. The moves are very similiar to those from THPS4, and there are no time limits except on goals. However, you can get off your board and jump onto obstacles and buildings. Again, there are secret characters, videos, and levels in Underground, which makes gamers want to come back for more. The graphics are the best yet and there are tons of songs on the soundtrack. There is a ton of freedom in this game with expansive levels and many creating modes. For instance, you can create a park, goals, skater, or deck. It has amazing replay value and may just be the best action sports game ever. I would rate it a 9.2 out of 10.
