Lioden is a fun game where you take on a male lion and strike out on your own to expand your territory, fight enemies and rivals, claim lionesses to grow your pride and even breed a genetic line of cubs! This game really is quite fun and even a bit addicting. The community is just phenomenal and everyone is a real class A person. Nice, friendly, and willing to help out where they can. And it's free which is awesome.
