It's an online game, you live on an island with dinosaurs. You can tame them and ride them. You build stuff, if you are mean you can loot people's houses. It's fun, I got to lvl27 and my tribe and I have tamed 2 raptors, a ducky, 2 mini t-rexes, 5 of those spitting small carnivores, and an eagle. We are working on making tranq arrows so we can tame the big t-rex >
