How many GB is Gargantua?

2 GB

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

Build your spaceship-city Gargantua. Forge industries, bend the free market, trade between planets, and defend your growing wealth. Every bullet is bought or produced in a simulated economy where a single mistake can shatter supply chains and trigger interstellar crises. In Gargantua, war is money.
