War Dragons is a phone game that Blaclighting has been playing for a long time now. He got me (Mael) hooked on it. It's simplistic in design and actually pretty fun to play. You basically build an island that you can defend in realtime if you choose too and attack other players. It's kinda Clash of Clans ish but instead of building hordes of things to attack you breed and level up dragons. It's actually pretty fun and simplistic and I definitely recommend people to try out.
We have a league there called ForsakenOrder than you can join once you hit level 4, 5, or 6. Can't remember now.
