Great Mistake Information from @CivWikia

[joncnunn]

the great mistake simulation must run on the Civ4 engine, where pollution from fallout tiles actually counted towards global warming ;-) (if i remember correctly).

You're thinking Civ II/III. Civ IV eliminated whack-a-mole pollution tiles in favor of a (local) health mechanic and fallout tiles were also represented as pollution.

If only it used the Civ4 engine.....

All someone would have to do would be to send a worker (who's probably busy having coffee and donuts otherwise) to scrub the fallout for a few turns, and problem solved!
