Dark age of camelot is still alive and kicking! yes, we have a much smaller population than we once had, but the game is still going strong! There have been many changes to the game over the years, the biggest one yet is the new Ywain servers (10 of them) recently created and clustered together to make one big, big server, where everyone has been move to, so that they could close down the old servers and migrate everything over to newer updated computer systems to keep the game alive and kicking. DAoC still has one of the best RVR systems around, which keeps peolpe coming back to experience it again and again.
If you find yourself, re-opening old accounts, you have the opportunity to transfer your old toons to the ywain servers and get caught up in the action once more. DAoC, has reduced the size of the different servers down to 3 main ones, Gaheris (for all realm pve excitement, good place to get to know the different toons from all the realms) Mordred (the player vs player server, where it's kill or be killed, nonstop action) or the Ywain Servers with the ToA expansions (no more classic, roleplaying or other clustered servers, anymore)
In my humble opinion, I still think it's worth checking out, even for just a little while. Who knows, you might like what you see and stick around a little longer, but in the end, only you can answer that question (about is it worth it?) I think it is...come back and find out for yourself!
