This game is best when you invite all your friends round to play world tour with ALL the instruments, bass, guitar, drums and microphone.
You can play one instrument alone, perform as a band with a few friends, or even go online and rock head-to-head or as some sort of Internet supergroup.

The selection of songs is varied as there are over 80 different songs to choose from

It lets you download, create and share original music.

The big new feature in Guitar Hero World Tour is the music studio. It lets you create and share your own tunes, as well as download songs from others. Should you watch all of the tutorials and put in the time to learn the complicated yet robust program, you'll be able to produce some amazing results. The bad news is that you have to put in a lot of time and effort because it's incredibly difficult to make music creation a user-friendly experience on a console, but it's near impossible if you force people to use a fake guitar. To make matters worse, there's no way to add vocals or lyrics to your creations.

World Tour has a Career mode, but it involves little more than playing sets of songs to earn money and unlock more songs. You have some control over what order you tackle the setlists and can personalize your rocker. You can even build custom instruments, but your career is linear and not all that interesting.

For the most part, World Tour looks and plays exactly as you'd expect, but there are a few things it does differently; some good, some bad. Musicians' animations have been improved, particularly with regards to vocalist's lips being in-synch with the lyrics. The ability to customize your rocker's pre-and-post song animation is also cool--especially when you've got him or her doing the robot after a good performance and smashing his or her guitar after a failed song. The vocals constantly track your pitch, leaving a trail behind that shows how your pitch has changed. This is extremely helpful when you're trying to sing the right notes and intervals at the start of a verse in a song with which you're unfamiliar. Bass players get a new challenge to deal with in the form of an open note, which is represented by a large bar that covers the entire width of the note highway. You might not think hitting the strum bar without pressing a fret would be noteworthy, but as any bass player will tell you, it makes the experience even more realistic. Last, but not least, the game gives you a quick countdown when returning from the pause menu, which gives you a fighting chance at hitting your first notes.

Those are the new mechanics that work well, but there are a few that aren't as useful. When playing drums, you must activate star power by hitting both cymbals at the same time. While hitting the cymbals isn't hard in and of itself, hitting them in rhythm so that you don't lose your consecutive note streak is extremely challenging. Unless you're a skilled percussionist, you're probably better off waiting until your streak ends on its own rather than trying to activate star power. Guitarists will have to deal with the most unique and not-so-useful mechanic.

Guitar Hero World Tour is a huge leap forward for the Guitar Hero franchise. It's a blast to play with friends, the setlist is top-notch, and the music studio is a nice--albeit extremely complicated--addition.

Overall i give it 8.5 or 9 / 10
