Which game should I get?

COD4 for sure...

Thats a hard choice. I have all 4.

I would probaly say GTA IV to start, it has an awesome story, and even better online play. It will last you a LONG time, Halo 3 is fun if your into arcade shooters, COD 4 is good, but I prefer Battlefied: Bad Company. And Gears of War is great, and GoW 2 is coming out soon too! I say GTA IV first and the other three later on. By the way: if you get xbox live, add me, I'll help you get some achievments, My gamertag is Spruceman2002. ( Just tell me I gave your my gamertag here). Have Fun!

All of them are great games but Halo 3 is kinda old already, theres gonna be a gears of war 2 coming soon, COD4 is still alrite the online gameplay is awesome with customizing your own gun, GTA4 finally has better graphics and you can team up if you know someone else who has GTA4 and destroy everything together.

I would choose COD4 or Halo 3 because they have great campaign and awesome online play. GTA4 has great story but not that good online. Gears is AWESOME, but I would rather wait until November for Gears 2

CoD 4 and Halo 3 have the best online play!

gears is overrated

halo 3

On a single console, up to two players can play campaign and up to four can participate in a versus multiplayer match through use of split screen. Through use of LAN or Xbox Live, up to four players can play together in campaign, up to eight can customize a map in Forge mode, and up to sixteen can participate in versus multiplayer matches. (Each console must retain their respective split screen limitations.) A public beta test of the game's online multiplayer features, as well as saved films and file share, occurred between May 16, 2007 and June 10, 2007.[33] Statistics from all games that are completed by players while connected to Xbox Live are also uploaded to the respective player's "service record" on Bungie.net.

Players must actively seek out other players through their Xbox Live Friends list, using the party invite system, or the LAN search feature to play multiplayer matches with their own custom rules and customized maps. However if they are connected to Xbox Live, a player can choose to have the game decide for them the exact rules and map to play on, as well as finding additional people to play against or with, using the "Match Making" system. A player will decide from a selection of developer designed "play lists" which each contain a certain type of way to play the game. The games contained within a playlist range from 1 vs 1 free for all, to 8 vs 8 team play. Often focusing on either deathmatch games, objective games (e.g. Capture the Flag) or a combination of the two.

Like other multiplayer Xbox 360 titles, Halo 3 uses a customized version of TrueSkill ranking system for 'matchmaking', or the automated grouping of players of similar skill. Halo 3's matchmaking system is based on two different measures of player ranking, skill and experience (based on the number of 'rating points' or EXP, respectively). Skill is the numerical TrueSkill rank of the player in a given multiplayer mode. The TrueSkill ranking is affected by both wins and losses; wins against a much higher ranked opponent will rank a player up faster, while losses against players with lower ranks will cause a player to drop in rank faster. The experience system is linear, with a player gaining experience for winning a game and losing experience for quitting or otherwise leaving a game, with no effect for losing a game.[34] To help players have an enjoyable time online, a new feature dubbed the "****** button" allows players to mute annoying players in the game quickly and easily from the in-game scoreboard view.[35] Like Halo 2, Halo 3 supports downloadable content and updates
