How many GB is Ian's Rocket?

2 GB

That is less than the typical Strategy game, which needs about 3 GB.

Leave at least 8 GB free: games need headroom to unpack updates.

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

A history-based, strategy, open-world game in which a nation's economy is built from scratch by utilizing all available resources. Create cities and wonders, hire labor, sell crafted products, and build armies. Meet historical figures who will either fight to stop your efforts or trade with you.
