Many of those people who started back at the begining, during the Halo CE DUKE days are now grizzled ancients with careers, children and a 401k. The true fans who have followed the series over the years do not play as often because of LIFE keeps us busy. Many of us do still play, when free time allows.
I remember hiding in the base in Gulch to stay alive as I ran to the fridge to grab another beer, the five people playing in the kitchen saw me and began a mad scramble to find the body I left behind.
I remember the first time we planted the bomb on Zanzibar, sweating and swearing at each other across continents as the timer counted down.
I remember trekking across Sandtrap with a bloody gravity hammer across my back and a flag in my hands, hoping they would make it with the Hog before the Chopper found me.
I remember yelling obscenities aftet sticking a grenade to an opponent only to have him put his fist to the ground and glow as the grenade was flung off and detonated next to me, only to see a familiar face materialize out of nothing and stab the enemy in his head.
I remember the forums, always cries of sacriledge and treason. Always.
