How many GB is 6600: The Park?

10 GB

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

Leave at least 17 GB free: games need headroom to unpack updates.

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

You are an investigator sent to an isolated prehistoric park sealed after a "containment breach." Facilities have collapsed. The former tourist zones are now hunting grounds. Your mission: uncover the truth behind the disaster, gather evidence, and reach the evacuation point before it's too late.
