How many GB is Collapsed Horizon?

2 GB

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

Travel between galaxies, dig planets, collect ores, sell them, upgrade your equipment, and earn your ticket back to Earth.
