Dynasties of India introduced the Palm Grass terrain, made entirely from existing assets – it’s literally Palm Trees on Grass 1. In a similar vein, here are some more suggestions for forest terrain types that reuse existing assets, but which I think would make some things easier for map scripters and scenario designers.
Separate forests for Mediterranean trees: Mediterranean Forest is a mix of olive trees, cypresses, and Italian pines. It would nice to have Olive Forest, Cypress Forest, and Italian Pine Forest as separate terrain types.
Non-Snowy Dead Forest: The current dead forest has snowy ground (as well as snowy bushes mixed in) so isn’t really usable on non-snowy maps. I’m imagining something more like this:
Scenario Tree Forest: A forest made up of Scenario Trees A–L.
The scenario trees started life as the default Oak trees in alpha versions of AoK, so this style of forest appeared in some of those:
Summer Oak Forest: Made entirely from green, leafy trees, e.g. these ones:
Lighter, Taller Italian Pines: These appear on some prerelease screenshots for DE, so the assets obviously exist. Here’s an example (from the DE screenshots on Steam):
