I’ve finally decided on getting my boyfriend either rock band or guitar hero for Christmas. Which one is better? And when you state your opinion I also need to no what all accessories I need to get. I figured I’d just start with the guitar and get the other instruments for other occasions. But do I have to buy the video game to go along with it or does one come with it? I no nothing about either one of those so your help is appreciated!! Thanks! 
Rock Band 2 is the highest rated and has the most replay value out of all of them. It has a great career mode that puts Guitar Hero to shame. Rock Band also has a HUGE amount of download content, Guitar Hero is very limited.
