There have been quite a few. But, my most significant would have to be playing Halo: CE do the first time on XB. My brother and I marathoned it over Thanksgiving weekend 2001. The graphics were amazing to me in many parts, and the gameplay, especially the gun play, was the best I had ever felt.
I had been gaming for nearly 20 years at that point. But, Halo really reignited my love for the hobby. Also, those times per the game with my little brother are among my most cherished memories
