I dont know if this can be considered a new guitar hero game, to me it just seemed like guitar hero 4 just with different songs. I know your going to say "omg thats all guitar hero is about", but I own guitar hero 3 and 4 and there is MAJOR progress over the games with different modes and obviously the whole band in guitar hero 4 but at least they all had a story to them. This guitar hero was just here's a playlist, play it, you unlock new songs. I kind of "cheated" (if you can even call it that) i didnt like this guitar hero so i just went to quick play and picked the songs that i liked and played them and then sealed it. If you are a die-hard guitar hero fan then this is the game for you if you liked guitar hero 4 (who couldnt) i was just expecting more. In the end i felt it was guitar hero 4 all over again, the wii did add asome excusive features though but unless you had a wii i guess there isnt anything new for you.
I only played this game for about 10 minutes. I tried 3 different songs, guitar only, in career and quick play mode. Each song had at least 2 video pauses -- the kind of frame drops you might see in a laggy online game, but I wasn't playing online.
For a rhythm game, the frame drops were inexcusable. Seems like Harmonix was so intent on boosting the visuals, they forgot about the actual game play.
I'm a big fan of Guitar Hero and have always preferred it to Rock Band because the game play is more challenging and I liked the Guitar Hero songs better. Based on what I've seen of Guitar Hero 5, Rock Band is the better choice, because whatever else happens on the screen, the next notes are always smoothly streaming forward.
