Played for many years from about a month or so after release. (I bought a new graphics card for everquest 2, but it didn't work so I couldn't play it, I wasn't that interested in WoW but for some reason I got that and never played Everquest 2) kept changing characters, deleting them, changing servers though so never got that far. I didn't really run instances until TBC as I had a few bad experiences (nothing really looking back on it) the social phobia made me a solo player and didn't look for a guild etc. Though at one stage I was in a guild that started on Karazhan, but it split up not long after and I quit, then I came back a bit, played WotLK a bit, got to about 77 and quit again.
I started playing Aion recently again, but it isn't as good really and I'm too much of a pve/soloist, and a few of the things in it are making me lose interest.
