Add more vegetation (as Terrain Features):
(Similar to "Lush Grass" and "Shrubs" and "Barrel Cactus" and "Mangroves" and "Swamp" and "Bog" and ... .)
- Spilt remaining normal Forrest Types: deciduous forest (Leaf) and corniferous forest (Evergreen)
- Transform current Bonus Ressource Cactus into Terrain Feature Cactus
- Add further Forrest Types (but I must still refine my concept)
- Add Lichen and Moss (because I really need them for my concept, to add some more Food at specific Thundra Types)
- Add Hedges and Thickets (which I want to have for completion to e.g. add Birds there)
- Young Forest and Burnt Forest (just for diversification but also for Events)
....
Add more non-vegetation (as Terrain Features):
(Similart to e.g. "Rock Reefs" or "Tar Pits" or "Flood Plains" but this time more on land.)
- Volcano (which already existed)
- Flood Plains I already created and added to Plains (just mention it again)
- Nutrient Rich Soil (similar to "Flood Plains"), Nutrient Poor Soil ( had not thought about it but your idea is interesting)
- Sharp Stones ( basically more or less an obstacle in Flatland that Pioneers can remove by "Pioneer Action" digging up --> giving 20 Stone)
- Huge Rocks ( basically more or less an obstacle on Hills that Pioneers can remove by "Pioneer Action" digging up --> giving 50 Stone)
- Impassable Mountains I already created and added to Plains (just mention it again)
- Ore Rich Mountains / Silver Rich Mountains / Gold Rich Mountaints / Gem Rich Mountains ( Similar to my "Impassable Mountains" as Terrain Feature on Top of Mountains)
....
And more (temporary) weather effects (as Terrain Features):
- Tornado (which already existed)
- Blizzard I already created and added to Plains (just mention it again)
- Fog I already created and added to Plains (just mention it again)
- Sandstorm I already created and added to Plains (just mention it again)
- Rain
- Drought
