Raft is an open world RPG/Survival game. You are stuck on a 4x4 raft in the middle of the ocean, and a hungry shark knows you're a great way to get his next meal. With your hook you can grab for different materials to repair and expand your raft, and if you are lucky find some food to grow. If you make it to an island you can get wood and stuff, but don't let your boat drift away. I've really enjoyed playing this with my brother and it's become one of my most favorite games.
