I don’t know anything about video game design or modding, so I have no idea if this suggestion is a possibility, or a completely stupid suggestion from an ignoramous. But would it be possible in the game, or for a mod, to make it so crenelated walls could snap on top of fences? The Nemedian crenelated walls have a fantastic look, but like all of them, they’re far to low to be realistic battlements. If they could be put on top of fences though, they’d be just about perfect for battlements.
The game’s mods feature tall battlements and half-walls, and even shorter ones.. These can be used to build nemedian crenelated walls.
