An amazing game.. (obviously)
Flaw No. 1
The strap on the guitar is a bit meddlesome... For instance, it tangles up easily and it isn't all that comfortable if used without a shirt on. But otherwise it's fine.
Flaw No. 2
The online download costs are ridiculous. If they continue to put a pricetag of $2 a song for ALL the guitar hero one songs, it would cost up to $90 for the entire gh1 track. The downloads also come in packs of 3, so if one song is unwanted in the bundle, it's money down the drain.
Flaw No. 3
No online play. I was hoping to receive xbox live combatibility (other than leaderboards) so i could do co-op or head-to-head with friends (or even random people over live). But good news is... Guitar Hero 3 is supposed to implement this idea. Flaw No. 4
The character models are extremely odd and some of the animations are over-redundant. However, this doesn't really matter at all considering the rhythms in the game are most important.
Flaw No. 5
Wait... I don't think there is another flaw..
