Same here. I’m not really a gamer outside of GW these days. Been playing since ~2008 (I think).
Still never bored with it and no interest in investing a bunch of time that I currently don’t have getting better at a new game I probably won’t get the same mileage out of.
Couldn't claim that it's the only game that I've ever played, but it's the only game that I've played consistently since 2005 with occasional year(s) breaks in between.
Got into Diablo 3 for a year or so when it released. And tried messing with Divinity Original Sin 2 for a little bit a couple years ago.
Guild Wars left too big of expectations for both PvP and PvE in games.
I have played many online games, for one reason or another. Too many to count or name. Probably tried every major MMO at some point. Never really stuck with most of them. Except Aion & Age of Conan, which is probably my favorite MMO because of the lore. For me, GW was unique in its economy. One of the primary reasons I enjoyed it so much long ago.
never played any other online game before or after.
Been playing online games since I was a kid trying to frag out in Quake II.
Now, Guild Wars is my favourite online game ever and second favourite game of all time, but it is certainly not my only online gaming experience.
Begin video games 1985-86 with Atari xxxx (not remember model, 5 years old), 1987 Nes, 1988 Commodore 128D, 1991 SNES, 1994 Playstation 1, etc ,etc. Play online since 2006, my first PC Gaming with GW for first online experience (and GTA SA 2004 online unofficiel 
fun), but i play many many games online, MMO, FPS, etc. Probably way too much played at video games..
My older brother got me into MMOs Guild Wars being the first. I loved it instantly man. Around 2008-09 I got into World of WarCraft. That was a cool experience too, the flying mounts was the highlight for me. Now I’m back like I never left 
I have played a few other but but this is my first .
