Your wiki page has a big mistake based on assumptions.
The largest city size is 2km x 2km, and the most cities per region is 16. However, the regions with 16 cities only contain the smallest size cities. The regions with the largest cities only contain 4-5 cities + one of those wonder things. I think you should just remove that assumed math from your wiki all together.
according to maxis there's only one city size, and that's 2x2km. there's no such thing as small cities and big cities. Zimmah (Wall/Contrib) 02:01, February 19, 2013 (UTC)
Could we remove the "Does not actually work" quip in the "differences" section? It's so hard to find legitimate information about this game without reading about the problems.
