How many GB is Mouse World?

10 GB

That is more than the typical Role-playing (RPG) game, which needs about 6 GB.

Leave at least 17 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

You are a human who has been transformed into a rat. Your objective is to find your human body in this RPG game in a medieval world. You will have to survive all the dangers that may arise along your way.
