The game is not dead, there are still quite a number of people playing it. It has got into a bit of a rut, but still runs well. It is a very social game with alliances competing against each other, and in a good group there is a lot of chat and fun.
Its main advantage is a short time commitment. Each realm lasts for 14 weeks, there is a winner, then everything resets and starts again. This gives you many opportunities to try new races and techniques and meet new people in new alliances.
It also has good customer support, unlike all the other games I have tried.
It is, however quite a small game now, and Pixel tend to concentrate on newer and bigger games. But come and try it out and find a good alliance to give you help and advice.
