"Rock Band"
The "Rock Band" franchise changed music-rhythm games by adding instruments other than just a guitar. You and your friends can create your own rock band, selecting your instruments (guitar, vocals, drums or bass), your clothing and your band name. The game's objective is simple: become a world-famous rock band. To achieve this goal, you'll start off by playing in small venues and will eventually play for sold-out stadium crowds. Your band will play music from artists such as The Foo Fighters, Jet, Soundgarden, The Ramones and The Red Hot Chili Peppers.
"Final Fantasy XI"
"Final Fantasy XI" is an online role-playing game originally designed for the PC. Like past Final Fantasy games, you'll learn new spells and abilities as you level up your character. As you obtain higher levels, the enemies you'll face become more powerful; this often requires you to assemble a group to defeat them. According to Gamespot, it is easy to form groups of up to six players, and the game offers some tools for finding other players and groups.
"Burnout 3: Takedown"
For fans of racing (and the occasional car wreck) "Burnout 3: Takedown" offers high-speed racing against six other players. You can compete in a two-player "Race" or "Crash" mode against friends or online adversaries. "Race" mode is your typical race, while "Crash" mode requires you to crash your car in order to cause pile-ups and damage (the winner is the player that can cause the most carnage). The game also has "One-on-one" and "Co-op" modes that can be played online or offline with a group of friends.
