I tried AOC its still a pretty game however the cash shop is constantly rammed down your throat.
Asherons Call 2 just had the game started back up again apprently Turbine felt there was enough noise for it, AC1 is still going and if you sub to that you can play AC2 for free.
I always hear mostly good things about LOTR:O so if you invest some time into it you might find something worth playing for a good while.
Oh and it looks great still maxed out.
Aion is an Asian grind fest so unless that's your thing don't bother.
Given that game a try so many times but i just can't get in to it. It seems there's fuck all to do once you've done the tutorial...
Plenty of quests to do past the tutorial, it's not for everyone though.
I used to like playing my Zealot on Warhammer, keeping a zerg alive practically solo was pretty lol
The offence/defence targets in WAR were great.
On topic: I'm trying Lotro, I got bored of no healer classes in GW2 and the mindless souless pvp.
