Halo 2 was a pretty amazing game i think anyone can agree, but for something generic i would maybe pick Conker Live and Reloaded as the best game for me. The singleplayer was great and really amazing looking at the time, and the multiplayer was incredibly fun. Now the worst... Really hard to think of what i could claim to be the worst honestly. Its so hard that ill use one of the very first Xbox 360 games as the worst instead. Blacksite: Area 51. Area 51 on the Original Xbox was a crazy good and fun game and i could play it 10x more times than i would have played Blacksite. The graphics were crap, the story was also crap and didnt feel like any of the characters were relatable or important, and the gameplay was especially bad. All around it was a really bad game and i would probably give it a 1/10 and i dont do that for any games lol.
