I’d like cities to be able to be a radius of one tile larger, an additional 16 tiles. The prerequisite could be a tech, Mass Transit and a city size of 18 or larger.

Mass Transit could unlock a new wonder, the Bullet Train – Rail travel distance increases 50%.

I put this here because the only way it would be practical would be with the Megopolis.

New resource: Bio-diverse hot spot.
A bio-diverse hot spot has an unusual abundance or diversity of flora and/or fauna. This allows eco-tourism and research of things such as new medicines (justifies the bonuses). +1 hammer, +4 trade, +1 health.

These would only appear in unimproved tiles. The distribution could be: Jungle 50% (health hit nullified), forest 30%, plains 5%, grassland 5%, ocean (near the coast, or what’s the point?) 3%, tundra 1%, desert 1%

Hmmm complexed..:confused:

SkippyT - your sig is longer than the five lines of default sized text allowed by the forum rules.

Please shorten it.

I believe there is a mod that allows the city radius to expand into a third tier of tiles. Check the mods forums.
