I also want to play a rogue or assassin.

No more kill 10 X quests!!

I have Guild Wars, the first one, and I beat the story back in the day. However, it doesn't have a rogue or assassin class. I know the expansions do, but I'm too broke to buy them.

I'm trying Atlantica right now. It seems like a fun game, but it has no rogue class. The story seems immersive.

I'm going to try Requiem and Dungeon Runners.

How are the quests in long term in all of these games?

I played Everquest back in the day, and it was very immersive but I'm afraid to go back to it. And I can't afford the monthly fees.

I played LOTR, and it had great quests. However, it has monthly fees.

most of these have a rogue class of some sort, enjoy!

nice

Taking a quick break from Runes of Magic...great game, I recommend it highly. The servers are packed right now and every zone has tons of players in them. Can't say enough good things about his game.

There is a rogue class as well

 Wow thanks! I'm going to try Runes of Magic. It looks like a mix between EQ and WoW.

It's more of a mix between Urine and Feces.

You might as well play WoW.

Yeah i'm playing RoM and enjoying it so far. It does, in many ways, remind me of WOW apart from the personal/guild housing, dual class system, PK's on the PvP server and no horde/alliance.

I can't comment on "endgame" since i'm still a relative lowbie in RoM (19/18 priest/mage) and don't have that much time to spend gaming anymore (like i had when i still played WoW).
