Guitar Hero 4 is an exciting game that can get very addictive if you are a fan of many types of music. The new instruments included into the game are very fun to use espacially to the drum set. Although the signal to the drum set though can be interupted very easily by a small object or someone passing by. The vocals are very accurate and can detect even the slightest blip of sound you make. The game offers more than the last 3 created. It allows you to create more songs of your own and if you wish you can get upload your music and share it with others. The quality of the game is worth nearly every cent. The laid-out note tracks, the limited career modes, the difficulty of the music tools and the poor quality of the resulting songs can affect your experience with Guitar Hero 4. The included new instruments like the drum set and the microphone if you get them can greatly increase your level fun and expertise in the game. Its a great way to overcome challenges and a great party game to play with friends and others. The sound that comes from the music can depend on your speaker system but overall if you hear the music then in my opinion its great quality. Overall i recommend that music lovers and people who like to play Guitar Hero games to buy this game because its a much better and upgraded version of the past Guitar Hero games.
