I'm going to have to go with Halo Reach. It had very nice visuals, some of the best graphics out now, and had very amazing gameplay. After playing the fist four games, if you count ODST, you can tell Reach went back to it's Halo Combat Evolved roots and modernized it with lot's more to offer. As if the gameplay and formula wasn't already great, they added the very fun and useful armor abilities. Master Chief is no doubt one of the best characters in the video game world, taking a break from him wasn't a bad choice because Noble Six was a great idea, not only can we change his appearance, we get to be him. That and it will also make Master Chief's return a lot more epic. Online is amazing, and the assassinations were a fantastic idea. I won't say it's better then Combat Evolved because it is a true classic. But Halo Reach is by far one of the best shooters and game, period, out now. It delivered a great experience and had lot's of difficulty. Thought you were good at Halo? Think again.
