I played EQ1 since the start of it back in 1999 to 2007. Played a cleric (main healer) that whole time, with no alts even close to max level. I ended up guild leader for a few years after I lead raids for years prior. We never got to the bleeding end game content, but we had a blast and got there with casual players, no mandatory attendance. That was quite a rare setup for EQ1 where raiding even year old content was pretty demanding and still required rough grinding prior to for access to the high end raid zones.
I tried WoW for around 4-6 months. Got a Pally and Warrior to around lv 40. But I never got into it like EQ. Then I tried EVE for a little less than a year, until I got ganked in high-sec and lost 90% of my assets. Sucked...that game is ROUGH to get started. After that is have been the wait for SWTOR and here we are!
