Diablo 2 & it's expansion LoD is a great game, much better than the original Diablo.
However Everquest blows it out of the water. Everquest is full of zones to explore monsters to kill and a huge amount items and loot.
Everquest currently has 15 races to choose from:
Barbarian
Dark Elf
Dwarf
Erudite
Froglok (Frogs)
Gnome
Half Elf
Halfling
High Elf
Human
Iksar (Lizards)
Ogre
Troll
Vah Shir (Cats, IE: Tiger, Lions, etc)
Wood Elf
Each has their pros and cons.
Everquest currently has 16 different classes to choose from:
Bard
Beastlord
Berserker
Cleric
Druid
Enchanter
Magician
Monk
Necromancer
Paladin
Ranger
Rogue
Shadowknight
Shaman
Warrior
Wizard
Each has their own style of play.
The game currently consists of:
EverQuest Classic (Original Game)
The Ruins of Kunark expansion
The Scars of Velious expansion
The Shadows of Luclin expansion
The Planes of Power expansion
The Legacy of Ykesha expansion
Lost Dungeons of Norrath expansion
Gates of Discord expansion
Omens of War expansion
Dragons of Norrath expansion
Everquest has tons of places to explore and things to see and do. You can play for years and still not see or do everything that is available. Each expansion adds more zones, and content.
I would suggest reading about the different classes/races and pick one that sounds fun. Try a couple out and have fun deciding what you want to play or do. Pick a class you enjoy playing, if you don't like it try a different one. Everquest is a grouping game you'll meet new people and make new friends.
The Platinum edition
-link- costs only $20 and contains all the expansions except the latest 2 (Omens of War, and Dragons of Norrath). It comes with 30 day free paid subscription. After your first 30 days you will have to pay a subscription fee (about $12/month). The platinum pack is the best deal for starters.
At first I was hestitant to play a game that required you to pay a monthly subscription, but after getting started it was well worth it. Everquest is a great game and continues to be so. It is always changing and being updated.
Welcome to the world of Everquest!
