Personally I had more fun playing Xbox 360, it was a hard decision because Halo 2 was amazing on the original Xbox. I choose the Xbox 360 because of the all the memories I had when I was younger and all the moments I had online with my friends. The reason that really outweighed my decision was that the Xbox 360 had plenty of more games than the original Xbox, some of my favorite games that I had played on the Xbox 360 was the Gears of War series that I absolutely loved and had played the story mode more than once, the second game that I went to the store and bought again was Halo 3, I think many people have played Halo 3 and realize how fun it was and how the custom games were classic and I do not think a game like Halo 3 will ever be released and have the same feeling.
