Green Day: Rock Band (PS3) vs Guitar Hero 5 (PS3)

Green Day: Rock Band is a music video game developed by Harmonix Music Systems, published by MTV Games and distributed by Electronic Arts. It is the fifth major console release in the Rock Band music video game series and, like other games in the series, it allows players to simulate the playing of rock music by using controllers shaped like musical instruments.
The game's soundtrack consists of songs by the popular punk rock group Green Day. Green Day: Rock Band will feature virtual depictions of the three band members performing the songs in new venues designed for the game. The game will incorporate existing Green Day songs already released for the Rock Band series as downloadable content, and will allow players to export its full tracklist to the other Rock Band game titles except The Beatles: Rock Band.

Guitar Hero 5 is a video game which is the fifth main entry in the Guitar Hero series. Similar to the preceding title, Guitar Hero World Tour, Guitar Hero 5 is geared towards playing in a four-person band experience, including lead and bass guitar, drums, and vocals. Guitar Hero 5 adds several new features, such as drop-in/drop-out play, bands composed of any combination of available instruments, a Rockfest competitive mode consisting of several various scoring mechanisms, and both song-specific and general Challenges to unlock new avatars, clothing, and other extras in the game.
