Yes and no. First off, a lot has changed. If your fond memories include stuff like going to Oasis or Paludal and seeing a lot of people, getting in a group, and having fun while barley surviving against orcs and what not, then no. The level 1-60 game is now either A)solo or B)get PL'd.
The game is mostly about the high end now. I always have the same memories, with eq being my first mmo and longest played. I'd think "Hey, if i go back, it'll be like old times. I can start a new char, play through my old stomping grounds...high keep was the bomb!" but i;d go back, find out that every zone is dead, except for the newest expansions zones. I sat in High keep for 3 days, 16 hours a day...not a single other person the entire time. I quit again shortly after.
EQ has lost its magic for a lot of people. It's a dieing game really.
