It is a awsome game with great gameplay.
The Good: The music... its just great. Some songs you may not know, and others are just classic to you. The game is highly addictive, but, with willpower, you can stop. The Guitar is really great and makes the game way more fun than just a wiimote.
The Bad: Thinking.....oh yeah! The difficulty can get extremely difficult sometimes.
Two important things in the game:
Sound: Without sound and music, this game wold be nothing. the music makes the game come alive.
Gameplay: The gameplay is pretty basic, but it gets loads of fun. The main thing in the game is really the Music/Sound.
Overall: This game is a great one. The Music/Sound is awsome, and he gameplay is what makes it addicting. Theres no point in renting, get it with a guitar, NOW!
