I have had my XBOX 360 for nearly a year and a half now, and i have played lots of games on it, and most have been pretty good. Im here to talk about my favorites. Number 4 is Assassin's Creed. I loved almost everything about this game. The graphics and the and the sound were excellent, especially the graphics when Altair climbed way up high onto a tower and took in the view of the enire city. That really amazed me how good that looked. Then the action and combat was really fun and i loved using the hidden blade especially. I also liked how complex the missions were. That was real fun. The only thing I didnt like about this game was the confusing ending that didn't really resolve much. But I also liked the whole story plot except for the ending, I thought it was very creative. So all in all, Assassin's Creed was a great game that I loved to play. Number 3 is Call of Duty 4: Modern Warfare. I loved the campaign in this game, especially being able to play as a British S.A.S. member and U.S.M.C. soldier. I thought that was really great. The graphics and audio quality in this game were exceptional. Then this was probably the best game I have ever played online. Although the campaign should have been much longer, I still absolutely loved this game. Now I can't wait for COD 5: World at War, and possibly COD 6. Number 2 is Gears of War. I just loved the intense action in this game (especially the use of the chainsaw bayonet!!!). The graphics and sound really amaxed me. I played this one for about 12 hours straight when i first got it. It is extremely fun to play the campaign in one or two player modes. Online this game was pretty fun too. Now I just can't wait to buy Gears 2, I'm positive it is going to be amazing. Number 1 has to be the Halo franchise. Everything about these 3 games was absolutely amazing. The audio and the graphics and the settings were fantastic. The campaigns were extremely fun to play and i loved the storyline. Playing through the campaign in co-op mode in Halo 2 and 3 is also very fun. The weapons on the game had great variety and use. I loved all the weapons on the game. I also loved the variety of enemies. Everything about Halo, Halo 2 and Halo 3 was amazing, and they are the best games I have ever played. Now I'm just waiting the arrival of Halo Wars and Halo 3: Recon, and possibly Halo 4.
