Yeah, pretty much done. Not for the reasons ultimately most would express though. For me, it was a combination of things.
I had simply finally had it with my PC. I have always been a Mac person, my PC being for gaming and testing. Its performance fell through the floor though probably due to SpyWare or just random things that happen to PCs that never happen to my Macs. So I retired it. No more PCs. Very likely means no more Guild Wars for me either, since I refuse to buy a new PC just to play a game on, and I refuse to install Windows software on my Macs.
Also, much as I had fun post-Nightfall in my new guild pursuing titles with a friend there (and truly, I miss now not being able to log in and say hi), the most fun I had in Guild Wars was prior to Nightfall when PUGs were very common. Could actually play in parties in PvE entirely with people and that was the norm. That's why I play an MMO (or any online game). I loved those days. I PUGged a lot and had a lot of success and fun with it. Heroes all but killed the game for me having removed the PUG dynamic almost completely. I retired for a while, but came back and joined my new guild and pursued titles 2+heroes, but for me, its not the same. Started to become a chore despite having a good friend to do it with. I may have been motivated to try and stay playing and fix my PC if PUGs were still common, but I dont wish to return anymore and my PC is gone anyway.
Moved on to other things --> outside. Staying in shape. Picked up one of my old pen and paper campaigns and resurrected it in a new all-digital form with role-playing software that is abundant now and do that time to time to still have a gaming fix.
I miss Guild Wars sometimes, yeah, but I find I am missing days that are totally gone and wont be there even if I returned. I get enough just coming to the forums and reading a few topics and seeing what is going on.
