I have quit EQ2 entirely (I hate that game), and still playing WoW and EVE.
EQ2 has a LOT more quests and a lot more quest content. However it has absolutely worthless player-versus-player. I consider WoW PvP fairly fun (as far as carebear MMOs go) (I play in BGs daily and I play on a PvP server) but EQ2 PvP is pretty much a tack-on addition not really worth bothering with. EQ2 has far less variety in items and how they look than WoW. For instance, many items in EQ2 have the same model, just with different colors -- even with an item of level 1 and another item of level 40-50. Thats pathetic. World of Warcraft has, by far, way more items. I didnt like EQ2's auction system interface. WoW has a way better auction system. EQ has unnatural, odd character animations that remind me of Vanguard. WoW has fluid, well-done animations. EQ2 crafting I found was both frustrating and boring. EQ2 housing was alright but the fact that you are limited in the amount of items you can put in your house, and also by the fact that you cannot place most items where you want like you could in Morrowind or Oblivion (only certain items are placeable in houses, most furniture; you cant place your sword anywhere, you cant put plants or potions or anything down into your house, thats gay) -- that ruined it for me: housing in EQ2 is merely a bunch of worthless furniture, it has ABSOLUTELY NO FUNCTION in that you cannot put your cool stuff there. Useless housing system.
Immediately in EQ2 I got into a guild but then a leader started pressuring me to get ready to raid. I HATE RAIDING. Raiding is retarded waste of time.
Another extremely annoying thing about EQ2 and Sony Online is that you are extremely limited by the amount of characters you create and use. You can only make about 7 characters. If you want more slots, you have to subscribe to the goddamn SOE Station Access, which costs 15 more dollars per month! And then you only get about 6 more character slots! DAMNIT !!! In World of Warcraft you get almost 60 available character slots over different servers !!! In WoW you can make up to 10 or 11 freaken characters ON ONE SERVER. WTF is the problem with SOE? They want more ways to suck more money out of you, thats what. I hate that. Its very greedy and inconsiderate of SOE developers, I will probably never play another SOE game because they are freaking idiots.
I do not recommend EQ2. Play EVE or World of Warcraft, or try one of the new games coming out. Like Darkfall.
