DBZ Budokai Tenkaichi 2 is one of the best DBZ games that I've played in a long, long time.
There's also a tag team system where you can switch charecters during battle which makes the fights last much longer. Also the environments are like twice the size than the first tenkaichi so when you fight it actually feels you can go almost any where.
The music is great. To be honest I got sick and tire of hearing the same music from the actual TV series in the DBZ games from DBZ Budokai 1 through DBZ Budokai Tenkaichi 1. The music in this game is all rock and techno. Some song are a mixture of both. But the music fits the fighting sequences perfectly.
You still have a story mode which is jammed pack with moments straight from the DBZ series, movies, and DBGT. It took me 3 whole days intel I got in the Frieza Saga and gotten Goku to Super Saiyan. IT'S THAT FREAK'IN LONG. You also got ultimate battle, Tournaments, dueling, etc.
Overall this game is awesome. Whoever says DBZ Budokai Tenkaichi 2 is a crappy game they can eat dirt. They won't know what a great game is if it slapped them in the face and puched them in the nuts. Anyway this game is a must have if your a fan and it's 10x better than the first.
