Should i get guitar hero 3 for Playstation 2?

May be...

I find guitar hero boring if you are looking at a one player thing. If you plan to play with friends, go ahead bro.

I honestly didn't like Guitar Hero 3 at all. In GH 3 there are boss battles where the point is to make another computer boss mess up the song. That just didn't make sense to me, the point of the series is to get a perfect rating, not make the songs sound terrible.

GH3 for the PS3 is a lot better, just wait for Guitar Hero World Tour...

yeah it is good if your a fan of the series
