Awesome.
I do wish there was something more happening in the background, they seem too dark and boring. I understand this is more like what its like to be on stage, but it could use some livening up.The menus feel a little clumsy, I wish the navigation was a little less linear. The voiceovers are pretty dry, but for an instructional game, I can live with that.
I just hope they plan to put out a ton of extra songs!
Guitar ability before the game: amateur, but could play a few songs and took some lessons 15 years ago.
