Guild Wars games (both 1 and 2 but moreso 2) are not the typical MMO experiences. Honestly, I don't think any MMO without a monthly fee will feel the same. At least for me, I feel like I have to continue to accomplish things to justify spending money each month on WoW.
Guild Wars doesn't have this sense of impending doom if you don't accomplish anything, which is a good thing, not a bad thing. I feel I could probably play it as a full time MMO and I probably wouldn't even sink as much time into it which isn't a terrible thing either.
That all said, I will play both games.
