the game is really great but it has some bad points.
1. the charts are incorrect. their is many 3 notes that should be 2 note and 2 notes that should be 1.
2. more chart problems. take the song 3s and 7s. the path right before the solo is wrong charted. sometimes i hear notes that ain't played and sometimes its too many.
3. if you download the song "halo mjolnirmix" you can tap the last part. you don't have to strum a note 12 seconds after any activity! thats just insane.
but the songs are really great and i find the online function really good. much fun time. a partygame with much enjoyable time. worth buying, many says this is harder than gh2, i cant agree. gh2 is harder to get 100%, but gh3 has been made harder with incorrect charts
