I tried it out years ago too. I was drawn in more by the really impressive magic/special attack videos they had at the time than by the dragons (and was later dissappointed to find those magic effects never made it into the game). I did like the community focussed world crafting events, to tunnel to new areas etc, and fight off invasions. It didn't hold me for long though, as despite some of it being great design, the execution wasn't great, and the population wasn't very strong/stable.
