Cities Skylines Codexery — Data & Quality

We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

This is a fiction/fan codex: entries describe an in-universe canon. Our audits check canon and internal consistency — external fact-checking does not apply the way it does on real-subject codexes.

Recent findings (audit lane, verbatim)

Lars Wingefors — Lars Wingefors served as the Chairman and majority owner of Paradox Interactive, not its CEO; Fredrik Wester has held the position of CEO during the Cities: Skylines development and release era.

Fredrik Wester — Fredrik Wester did not co-found Target Games (founded 1982); he joined in 1994 and is a founder of Paradox Development Studio and Paradox Interactive.

City Hall — The entry incorrectly claims Houston's Old Market Square City Hall was rebuilt after a 1901 fire; historical records indicate the building stood continuously until 1939.

City Hall — The entry incorrectly states Thomas Jefferson is depicted on the lawgiver medallions frieze; documented lists of these figures exclude him.

Waste Management Service — Base game incinerators and landfills do not generate electricity or income; only Green Cities Recycling Centers generate electricity.

Waste Management Service — All base game waste facilities operate at a net financial loss without generating revenue.

Public Transport Network — The entry incorrectly states that the 441 tiles represent approximately 309 km² of total buildable area, whereas official specifications and widely accepted canon state the total map size is approximately 500 km².

Industrial Zone Authority — The entry title 'Industrial Zone Authority' incorrectly labels the Leeds City Region Local Enterprise Partnership (LEP), as no such real-world entity exists under that name.

Industrial Zone Authority — The claim regarding Office for National Statistics rankings is false; the South East region typically ranks higher than the Leeds/West Yorkshire area in both population and GVA, not second only to London.

The Mayor — The entry incorrectly lists tourism and high-tech manufacturing as specialized industries; official canon (Industries DLC) defines specialized raw material industries strictly as Farming, Forestry, Oil, and Ore.

Coastal — "Unlike the Temperate or Desert themes, Coastal-style maps feature static water levels" implies other biomes have dynamic water; in reality, all standard base game biomes (Temperate, Snow, Desert) feature static water levels with no tides.

Coastal — "harming local marine life" claims a simulation mechanic that does not exist; the game tracks water pollution affecting buildings and citizens, but there are no individual marine life entities or populations to be harmed.
