It's funny that this thread is inspired by Curl's, because my favourite XBox memory was inspired by my favorite Nintendo one. Two years ago my future wife asked what was my favourite Christmas, and I said '91 when I got my Super Nintendo. So she bought me a One and several games to recreate the moment from 25 years earlier. It ended up being especially great because my brother was home for the first time in a decade and we played Forza into the wee hours. A special moment.
A second epic moment has to be experiencing the original XBox and Halo for the first time. Playing coop with friends in university was like nothing before it and had that wow factor that only groundbreaking new experiences provide. It was like the first time playing Zelda or WoW.
