I played Guild Wars 2 for a while, which is radically different from the original Guild Wars.
The original was Korean only for a long time and has more of an isometric look to it, if I recall. Never played that though.
Guild Wars 2, on the other hand, is really not that great. It's yet another MMO where you spend your days grinding through, killing dogs and cats and bees or whatever the creatures were, leveling up along the way, for no apparent reason.
Then again, if that sounds like fun, have at it!

I second what BritishGeek said. Lord of the Rings online is really nice, and it's free.
Mind you, it's the same old same old. You grind through, killing forever to reach higher levels with no end in site, BUT, you get to do it in middle-earth.
When I played, I could care less about fighting. I picked the burglar class with my Hobbit allowing me to use "stealth", that way, I could sneak around enemies and just travel around the world checking out places from the books that I always wanted to visit.
I highly recommend it.
