Playing the full hour of the trial is just enough time to almost get the basics down. It's a survival game. You wake up on a beach almost naked and immediately need to survive. If you don't gather food and eat, you die. You don't drink, you die. Don't defend yourself, you die. You will die a lot while learning. After the very strong learning curve, the game is awesome. You gather resources to make clothing, armor, tools, weapons, structures, defenses, etc. You tame Dino's which all have different purposes. You can join or create and manage a tribe, then help each other survive, share resources an XP, etc. You can go to war with other tribes, plunder their riches, etc. There are caves to raid and gain materials and artifacts. They are still adding things to the game. I highly recommend purchasing ark.
