i've been playing the retail since it came out. GW isn't so much an MMORPG as you might think and its also not entirely dungeon-crawlerish. most exp is obtained by completing quests, as opposed to fighting the same monsters over and over. the extent of the MMORPG elements is the built in economy with crafting items and such.
items are more of an MMORPG feel where you don't just get them off a monster, but are required to craft it. stores are limited, as far as buying armors and weapons, so you really can't avoid crafting. and they give a fair share of them when finishing a quest.
what happens after ALL the quests are completed, i'll have to wait and see, but i hope there's something to keep it interesting, and i don't have to resort to fighting monsters, since in general, they're not too generous with exp from kills.
