The game's just as fun to play now as it was in its prime. It has the advantages of having one giant server where everyone goes, so it's still busy, and it's got more content now than ever, plus with the heroes from Nightfall, you can even successfully solo most stuff with yourself, 3 heroes, and a coupla' henchies. It takes a little bit to get used to the way the game works, but once it clicks, its lots of fun.
EDIT -
I'm again going to put out a call to arms to everybody who wants to play. If Xessive comes on board, that gives us another hand at the Lifesteak Sandwich tasks, and I once again renew my generous offer to COBRA. I know your misgivings, but seriously man! The offer stands, it's a good deal (the best kind, amiright?), you have friends to keep you from going off the deep end, and you're under no obligation to keep going if you decide against it in the end.
To further entice anyone who isn't currently playing, I'd like to reiterate the wide variety of amazing locations and the fantastic accompanying art that Guild Wars contains by showing you some more of my beautiful 8 jillion screenshots. The system requirements aren't super steep, so older systems can still run it, it's got an amazingly well-optimized engine, and it still looks really good even after so much time has gone by. Plus the community is still active and there are still lots of players around!
So here's shots, spoiler tagged just so they don't load before you're expecting them:
You've got wastes:

And more, JUST BECAUSE I'M CRAZY ENOUGH TO TAKE ALL THESE SO SOMEBODY NEEDS TO SEE THEM:

And I kid you not, this is the barest, most generic stuff I can show you. For me half the joy is just going around seeing all the cool new places, and these are just some of the general stuff. The initial campaign can be a little divided into regions, but you'll often note a lot of variety in where they send you from mission to mission, and there are tons of unique places that can't be so easily pigeonholed.
SO COME PLAY.
EDITx2 - Added a couple more shots because I'm insane, and put it in spoiler tags just to avoid people having to load them if they weren't ready to. Note also that they're a full 1280x1024 if you want to view them outside of the forums. They look decidedly more glorious.
