Meh, been done, been done better.
I gave this game a two because I thought that there where ways to improve it, and here they are:
1. It needs less frets. Six is way too many to keep track of.
2. It needs more technically proficient graphics, as opposed to stylized graphics.
3. It needs to have ratings on how you hit the notes; good, bad, perfect, etc.
Also, this is more like Frets on Fire than Guitar Hero, just so you know.
