@Rotcrafter Exactly. In the current vanilla version terrain do impact road building time but not the cost, which is rather strange. I'd add this in another upcoming mod (as suggested by @umbaretz ) for better balance.

perhaps roads should be more expensive in terrains like mountains and hills. i reckon this would balance this

@Paracalico now that you mention it, tying to development would work and AI wouldn't need to be taught that.

@umbaretz Thank you for the idea. It sounds reasonable to scale the terrain/vegetation debuff with development/prosperity level or something similar. Although the terrain info is hardcoded-ish iirc, to add buffs for compensation is not that hard.
Buildings are tricky and yes, teaching AI how to use it will be painful.

Its a great mod, and it does seem more logical for roads to work this way.

If you want to follow up on terrain theme - would be cool to make a building that can offset vegetation debuffs (essentially converging to grassland/farmland). I find it hard to believe that people living for ceveral centuries in a 100 dev province wouldn't be able to do land clearing.

So, you build it, and after some time it gives a bonus, counteracting the province penalties, after reaching farmland level building should self-destruct.

Hard part is teaching AI to use that.

I am not sure why some people downvoted it (currently at 3 stars) but thanks for sharing this, it made no sense building a road but having no reduced proximity debuffs.

i am actually suprised EU5 runs quite well on my PC so i personally didnt felt noticable difference though knowing for people with weak PC's or for case where we have big mod lists these checks could add up so having a lighter option would be best for those cases

@Mistah_X This mod maintains a list of possible candidate locations only, so the performance impact is limited at best effort. So far for my PC I didn't feel the performance impact (or maybe my pc is ♥♥♥♥ enough to lag at max speed already). Feel free to report if you feel the performance impact and I'll make an annual version!

how much does it effect performance? maybe yearly check would be better considering roads are a very long term thing and waiting a little bit more for getting the long term effects while saving performance would be a fair trade off

@DylanJack Thank for your advice! The game calculate proximity cost from location A to B based on the local proximity cost of A mainly, and that's why the lake-to-land prox. was fixed easily (i.e A-to-Lake unmodified, Lake-to-B cuts 99%, results in halving the cost). However, if we want land-to-lake prox. fixed too, the land-to-land cost of other adjacent land locations will be cutoff too, which would be kinda weird...

Hey, thanks for making this! Lake proximity being so bad was really bothering me. This fixes the proximity cost for going from lake to land, which is nice, but looks like proximity for going from land to lake is still high. Could that be fixed too?

skill issue

@OrdinalChaos this mod add a hidden situation to check global locations every month, if the road count is not zero, a location modifier will be added to totally compensate the debuffs. Thus the existence of any road compensate it fully already, even one single gravel road.

How exactly does this work? Do gravel roads completely compensate for the terrain debuffs or is it partial and the various road levels further decrease it?

你好，我准备做个建筑大修的，感觉你这个想法很棒，可能会借(抄)鉴(袭)一下~可以嘛~
