I've played on a couple of private servers, only particularly enjoyed the first server, to be honest. It's a fun game, provided you're not horrendously underlevelled and you have people to play with. I think it's the people as much as anything that make it a fun game, as I imagine is the same for all MMORPGs. High rate servers annoy me, as do those with horrible, low card drop rates.

I've not played properly for about a year. I had a lovely level 70 Mage.
