How many GB is Sime Is Back 18+?

3 GB

That is less than the typical Adventure game, which needs about 5 GB.

Leave at least 9 GB free: games need headroom to unpack updates.

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

Explore a mysterious world hub temple and travel to different worlds, collect shiny diamonds and keys, and unlock new levels packed with that nostalgic charm you’ve come to love. It’s everything you’d expect from a fun, lighthearted 3D platformer… Until it isn’t.
