I always found neutral territory 'gaps' inside civilizations borders so strange and ugly... Would like to suggest some methods how it can be fixed: - if some small chunk of neutral tiles is fully surrounded with single civilization borders - automatically join those tiles to the nearest country cities. I'd set such chunk maximum size to 5. - if mountain/impassable feature tile has 3+ neighbour tiles owned by one civilization - join this tile to the nearest city of this country. - Feudalism, Colonization and Industrialization each reduces tile cost (both cutural and gold) by some meaningful % (lets say 25%) - speed up border growth. This should make borders look more realistic, won't break balance at all in case of mountains/impassable features and add more strategy in placing new cities/buying new tiles, as you can grep more land faster if plan your city placement/tiles purchasing properly. What do you think?
