How many GB is Zusi 3: Aerosoft Edition?

11 GB

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

Leave at least 19 GB free: games need headroom to unpack updates.

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

Zusi 3 Aerosoft Edition is a train simulation for PCs, the professional version of which is also being used in railway companies for engine driver training purposes. This game is identical to the game Zusi 3 Hobby, but the Aerosoft version has an English language manual available and uses Steam to distribute updates.
