Compared to some of the newer ones, GH2 was short, awesome and incredibly addicting.
PROS
+ Great graphics and art style.
+ Pretty sweet song selection
+ Co-op is a very nice addition
+ 10 more songs than the PS2 version.
+ Excellently designed achievements.
CONS
- Some of the cover bands suck.
- Less songs than some of the newer games.
- No online.
- Glitched leader boards.
Seriously, some people have like 999,999,999,999 on Easy or something for a few songs. The gameplay is smooth sailing and the colored circles are very fun to look at. (Weird huh?)
This baby is like, 20 bucks at Gamestop for a whole lot of enjoyment. Highly recomended.
