How many GB is Mr. Billion?

1 GB

That is less than the typical Simulator game, which needs about 4 GB.

Leave at least 7 GB free: games need headroom to unpack updates.

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

Mr. Billion is an idle life and economic simulator where you'll rise from a homeless nobody to a wealthy tycoon! Make smart choices, climb the career ladder, and build your luxury life. Tap your way to billions and live like a true money king!
