I was a great lover of NWN, etc
Sounds quite similar to me. NWN was 'the' game, played it for a good 3 years, even got me into 'roleplaying' which to be honest I enjoyed a lot, and met some awesome people.
Have played NWN2 near to the end, but the multiplayer aspect to me pretty much died when I realised you had to actually download the world you want to play on from a website before connecting to that server.
GuildWars kept me occupied for a good while, along with the exp packs, brilliant game for different builds and PvP, but the PvE get's quite boring imo.
World of Warcraft, god damn the game, wasted too many hours playing this, good game, but it's pretty much raid get lewt which is +1% better and repeat.
On a smaller timescale i've tried RFOnline, City of Heroes, FFXI, Eve Online, none of which really appealed to me.
At the moment i'm playing AoC which is not bad, but far from great, yes it's nice to look at but take away the shiny graphics you're left with extremely buggy graphics options (increasing gfx increases fps in some cases), Fed-Ex quests galore (fetch this, kill this, take this) not much originality, which WoW seemed to have in a lot of its quests. Gameplay is still button mashing whether it seems original or not (click a combo, press 2 or 3 directions and repeat).
Pre level 20 it seems like a nice game, lovely detailed environments, but sitting at lvl 29 now I feel.. cheated I suppose, environments seem bland, no voice acting, same style quests, similar loot stats, can't see myself staying subbed after the free 30 day trial is up.
So, in my opinion, there's not a lot out there which is decent in the mmorpg market at the moment, it seems the mentality is 'if WoW can do it, then we can copy them and hopefully be as successful' and they improve upon nothing.
