You will need EverQuest 1 (the disc/s)
You will need several expansion packs.

If you have that (or want to spend 5 bucks to buy it) you should definitely check it out.
It's still EverQuest, but the leveling/zones/spawns/quests/most everything is very different.

There is a strong community and an average of about 300 people online at any given moment. Give it a look and feel free to shoot me a tell if you start playing (Uuvin)
