You missed the $30 early access so for full release it is $60. I play on PC. Two types, people vs environment and people vs people. I play PVE so I only have to survival the environment and the beast. Start in just skivvies on and Island called Ark. You have to survive the dino's immediately around you and you will die many times as you lvl up. Start my gathering resources wood, stone, thatch, fiber and construct basic weapons and tools. Cooked meat from kills and berries are food. Move from thatch huts to wood to stone to metal. As you gain lvls you can make a smithy forge, fabricator ect.. Eventually you are making rifles scopes, rocket launchers. Almost every beast is tamable and have saddles that can be made to ride and then you make them work for you. It is a survival game, resource management, hunting and taming, structure building and animal husbandry type game. Mating the dino's will create mutations and with a owner imprinting on said dino's you can create super beast that own most of the map. The map is huge as well with many different biomes desert, jungle, snow, swamp,plains, redwoods. Game play is on land, under water and in the air.
