I love this game. App convinced me to buy the full ps4 version when it drops Friday. I only play single player and dont expect an app game to have a ton of content tho so the lower reviews may still apply to you. I was treating it as a demo for ark tho and i liked what i saw. I am rating this as an app game and a demo. Do not spend money on this version as there are serious errors. Play by yourself for free and you will have fun. Honestly dont ever spend money on apps??
