I think it’s a pretty easy call for me - World of Warcraft raiding was some of the most fun I’ve ever had gaming. The pinnacle was probably when my guild got Realm First! Fall of the Lich King (25-man heroic). We spent MONTHS grinding away at it - we had the 10-man realm first achievement as well and could clear heroic with a variety of group comps, 2 or 3 groups per week would run on off-raid nights. But for 25-man heroic, we could clear the rest of the raid in 2-3 hours as I recall, so we’d take some swings at him on night 1 and then we’d spend 2 full raid nights on The Lich King - the final boss of Ice Crown Citadel raid and in fact the final boss of the Wrath of the Lich King expansion.

For SEVEN months we did this. He was tough af. He had a number of abilities where a single person fucks up and either the whole raid wipes immediately, or it rapidly snowballs out of control otherwise. So after a month’s long uphill fight, and with competing guilds just as close as we were, it was an INSANE moment when we got our realm first kill. It was such a ridiculous high, everyone screaming with relief and excitement. The realm second kill happened that same night, too - so we just narrowly managed to earn our server first kill.

We continued with realm firsts in the Cataclsym expansion on Sinestra, Ragnaros, and Deathwing. I got my first and only legendary weapon - Dragonwrath this expansion. And finally the Mists of Pandaria expansion was the beginning of the end for our guild as a lot of long time players like myself started falling off, so after earning #1 for the first raid tier, things slipped from there. I had a ton of personal victories in game too - after earning Dragonwrath, the most esteemed of all was earning the achievement Insane in the Membrane.

And yet - none of those other victories remotely compared to that first kill of the Lich King. It was truly a special moment.
