Pros
Pro Tons of replay value
You can easily spend hours just observing the world around you. Every creature has its own life it lives even when they are offscreen. There are no boss introductions. Enemies/creatures just come and go as they please. They have their own lives, and yours and theirs can intersect. It's an open world game so huge that it is nearly impossible to discover everything in your first playthrough. There is always more to learn.
Pro You play as a Slugcat
In rain world, you play as a tiny, cute slugcat, near the bottom of the food chain. Upon first playing the game, the movement system may feel a little clunky, as it features unfamiliar control schemes, and strange movement, but many who have mastered this little creature will say that he has some of the most in depth, and masterful controls in all of gaming.
