Although minimally improved, it is still the best rythm/music game out there to play.
With this version you get a few more songs, a few more modes, but nothing overwhelming that will make anyone a fan of these music game poo their pants for.
The graphics, controls, and so on can be easily compared to Rock Band, so if you have played the first one then you should know what to expect. There is a decent set of songs, although many of them are rather boring and unexciting to play.
It seems as if this game has also gotten to be a little bit disorganized. From quick play to career everything just seems to be effortlessly thrown in there (just as with GH:WT) I have noticed.
And speaking of which Rock Band 1 and 2 are much better than the rip off that is called Guitar Hero: World Tour. The instruments, songs, and mostly everything else just top guitar hero.
So overall Rock Band 2 is still a fun one to play even though it is easy to get bored of it very quickly. You can buy some overpriced songs for your own enjoyment, but this sequel can be easily considered a money drainer because you are paying for more songs to play and hardly any new content.
But still, Rock Band knows how to do it best.
