In order;
Formed the current longest-running guild with my friend on Shadowsong PvE, back in November of 2004 (game came out Nov. 20, 2004) - <The Dark Knights>; still a guild to this day, and he's still in it. Yeah. We were 17 and now we're 30.
Server first Onyxia/Molten Core clears with Apathetic on Shadowsong:

This led into being the first Fury Warrior on Alliance-side Shadowsong with a Maladath /swag /shame /poorrogues
First set of realm transfers opened up due to high populations on launch servers; lost a lot of friends. Became exactly what Apathetic needed; became Twice Forged, then, passage.
***Pre-nerf Twin Emps downed.*** Never did get C'thun without a shit ton of nerfs. Had to have been version 28.6 or whatever arbitrary fix/patch/casual-mongering-easement was necessary.
Right before Naxxramas I was banned for buying gold. Lots of gold. In Classic, 1k was a bit. I bought over 10,000g for $900. My first tax return. LEL. LESSONS LEARNT NYUKKA.
Missed all of BC. Much to my chagrin. Friends in guilds went onto US-9th Kil'jaeden (makaveli of US) RIP THE FEELS. Fuckers did pre-nerf Muru too. I watched and got baked. All the while wondering. Didn't have the balls or heart to remake a brand new account and do the grind to 70. Suffered by missing the best expansion the game ever had.
Came back during ICC-tier of WotLK. A lot of change, but PvP was outstanding. Came back because Blizzard unlocked my account. Wrote a giant e-mail, sent it off every month (got the idea from Shawshank Redemption :P), never heard a word. One day, "here ya go bro, go play them classic toons!"
Casual'd through Cataclysm, raced for server-first 90 on Sargeras-US in MoP. Never got it. Too many pros.
World-first parse on heroic Wind Lord *Heart of Fear* (10m), as a Prot Paladin w/ midwinter/SC alts; in DPS and healing done. I'll never forget it. Somewhere around 800kdps/350k healing. GG glyph of the battler healer solo tank.
Stopped after heroic Ra'den, for good.
Then came Nostalrius.
Some might remember me as Basecamp, of <SIX>. Took a bunch of randoms, became a quality guild with MC/BWL under the belt by the time Nostalrius collapsed.
UBRS #1 dps in Nost, no matter the classes against. Oh the fun of consecration in classic.
There's millions of memories in between all those. The game's been dead for me, for a long time though. But I'll always look back fondly. Always.
