They have done a lot in the last year to make EQII a nice medium between WoW easy and EQlive Hardcore. The addition of Echoes of Faydwer expansion next month will expand on 1-69 game and also build up on the end game.
The learning curve is still there. The world is vast and they don't hold your hand and guide you around like World of Warcraft.
If you can make it over that initial hump well then you have one hell of a game. Find a friend that plays, read the manual, make sure you pick up EQ2map UI (gives maps that show quest/npc locs) and use Ogaming EQII DB for quests.
