In my opinion it is a 4/5 because its great it has lots of things and elements to be discovered by players such as the crafting the exploring of islands. Also I like that it is open meaning it gives the players more freedom of what they want to do and not everything on every island is just walking and exploring because the terrain of the islands are harder than other games meaning the players have to think and create there own way to reach parts of the islands. I would have given it a 5/5 if it was more complex and diverse to how you complete and finish the game such as if there were multiple ways to completing the game or if there was a more complex and longer journey to the completion of the game. But I have to say good job on this game Raft its come far and its earned many good reviews.
