GH6 is much better than GH5 or Band Hero, the songs are better, the graphics are better and the overall gameplay is much improved. The story mode is interesting and draws you into the game. The only negative point is the game is a little too easy, especially when you take into account the songs are mostly hard rock and heavy metal. GH3 & GH Metallica are much more challenging. Overall though a good edition to the series.
This game is very good, a big improvement of GH5. The new story line part has added to the game and the songs are better than on GH5. Easy to use as well as I have the game on Wii and I find it more comfortable to use.
Although one thing I will say is they should make a Muse Guitar Hero!!
