Yes still play it.
This is my go-to game when i'm not playing anything else - i have returned to it three times now after breaks of around six months in between, and tend to play it for many months when I do. I'm lucky too to be in a guild where they don't care if you disappear, and welcome you back if you return.
It is still the largest and broadest of all games I've played. The scope is huge, and there is no effective ending or top-level for your characters. And there are new areas and new content added by expansions from time to time, some of which I have yet to experience or explore.
