How many GB is Check-In Chaos?

6 GB

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

Leave at least 13 GB free: games need headroom to unpack updates.

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

Run your own hotel — solo or in 1–4 player online co-op. Check guests in, cook and serve, run the spa and pool, hire staff, and upgrade your rooms from Standard to Luxury... before it all spirals into glorious chaos.
