so far i've played:
WoW
EQ
DAoC
Fallen Earth
Aion
Guild Wars

and now im curious about LOTRO, is it worth playing?
Is the game kept up to date? (patches etc)
How is the community?
anything i need to know about it?

Yeah, I love the game. The community seems very good and the game is updated regularily. Third expansion pack was just released.. at least I think it was the third one. I have played WoW, EQ, EQ2, Vanguard, EvE, Guild Wars++ and still think Lotro is one of the coolest ones.
