Keeping useful first-save observations
TF3 has interconnected cargo, transport and city systems; useful observations need the context in which they were made.
Plan the operation
Record build, mode, climate, difficulty, active mods and relevant values before changing a line. Preserve a copy of the starting save.
Check the result
Compare the same duration and inputs. A result from an edited Sandbox map should not be presented as a universal Tycoon formula.
