I'm A Hero.

A world where you are alone is not a world.

No, it's actually a world, and moreover, a world of your own, entirely at your disposal)
other animals will remain, right? well, you can play as a druid, turning the world into a PvE environment))
or into something else
in short, everything will be in your power, until some tiger, or lion, or bear, or wolf eats you))
