Music, music, music... it's the most important aspect of any Guitar Hero (besides a responsive controller) and akin to Madden's yearly roster update. After a disappointing outing with GH: Smash Hits, Guitar Hero 5 is a big recovery. This could be the newness talking, but this may be my favorite set list to date. I was happy to see a number of songs from my high school years make the list, including "Comedown" (Bush), "Smells Like Teen Spirit" (Nirvana) and "What I've Got" (Sublime). I can't say I'm completely happy with all of the song choices, but I enjoyed going through a majority of the songs. As with past versions, Guitar Hero 5's tracks are a little more guitar-focused than its rival, Rock Band. Songs offer something for every part, but without the massive breaks found in some Rock Band selections.
For the first time ever (and it's about time too), a Guitar Hero game is compatible with songs from a previous game. If you have either Guitar Hero: World Tour or Smash Hits, you can enter a code and download songs from either game into Guitar Hero 5. There's a slight relicensing fee (before heading to message boards to protest/ complain those money-grubbing execs, Rock Band required a fee as well), but it is worth it for the extra songs. DLC songs are also supported and even gain extras like Band Moments in the transition.
I'll refrain from using the word "mature" to describe the game's updated look and just say it looks much older than the "cartoony" look of past games. The visuals still have all of the style of past games, but characters have the harder edge seen in GH: Metallica. The returning cast of characters features an updated look and the game's guest stars, like Johnny Cash and Shirley Manson, are detailed right down to their smaller stage mannerisms, adding a sense of authenticity and style.
Exclusive to the 360 is Avatar support. You can import your virtual representation into the game and play through any of the game's play modes. The only time the option looks odd is when you are standing next to in-game characters, though you can replace the rest of your band with random (or player-created) Avatars if it becomes an issue.
