If you played on Sullon Zek and preferred it try
Wurm Online and play on the pvp servers. Wurm Online has some of hte same gameplay features of EQ: corpse runs, slow travel, automatic combat, first-person (it has no 3rd person), small (but noticeable) death penalty, map doesn't have gps, few other things. It's more of a sandbox than rpg, so keep that in mind.
Other than that there're lots of small MMORPGs and MMO sandboxes which have bits and pieces of old EQ. You just have look for it. Some of it's player-run. You won't find anyting which reproduces most or all of it, but some is really good.
Here's an example, but damn, you'll have to do the searching yourself because I don't have the patience:
