Great long term game. I've been playing for several years, mostly F2P, and it keeps me interested. Find a good alliance, it makes a big difference. I've heard numerous game style comparisons to clash of clans, but there are some significant differences. Also, lately it's had some lock up issues for me. Hoping they get that sorted out soon. Update: they updated the game for the worse, and it's become completely unplayable. It just locks every time. Can't play anymore. Dropped from 5 star to 2.
