I'm a fan! 
Most of the old comics can actually be read for free in digital format on the Elfquest site (elfquest.com), although the more recent stuff (especially Final Quest, which only came out a few years ago) you'd still have to buy in print.
The world definitely gets "bigger" after the Kings of the Broken wheel arc, with lots more characters introduced, and the stories get darker and more complex over time. Still, if you remember it fondly from your childhood, I do think it's worth checking out to find out what happens!
