  • I am tinkering with something similar right now, with the elf-equivalents being virtually illegal outside the borders of their own empire.

    So, here’s what I would suggest you consider:

    • First, discuss it with your players and make sure you’re not going to piss any of them off by doing this. If any of them were planning on playing said race, make sure they’re okay with the impact on their play style.

    • Consider the storytelling conflicts you want to explore with this. What encounters do you want to put your players through, and why? What themes are you looking to explore?

    • Consider the larger impact on other parts of your world. Try to make this more than a point that exists in isolation and a vacuum.








  • Like the other comment says, concrete is rocks of various sizes (called “aggregate”) mixed with a cement and other additives to change its particular properties.

    The cement is the really important point, because once water is added to the cement, it undergoes a chemical reaction which hardens it. Saying cement “dries” isn’t quite correct - yes, it stops being wet, but some of the water actually ends up incorporated into the molecules of the final cement. This is also why cement is really hard to recycle - you have to undo that chemical reaction, as opposed to asphalt which stays the same material.

    Fun fact: When concrete is mixed at a big plant, it begins curing immediately. Concrete being carried in those big mixer trucks needs to be delivered before it cures in the truck!



  • Specifically talking about asphalt vs. concrete:

    • Asphalt is relatively cheap vs. concrete. This is partly because asphalt is a whole lot easier to recycle than concrete, which is almost un-recyclable, but also because asphalt is a relatively “simple” material - it’s mostly petroleum byproducts and gravel.

    • Concrete doesn’t grip very well, compared to the relatively textured surface of asphalt. Especially when wet! This is why you often see concrete formed with “ridges” or “bumps” cast into it. However…

    • This also makes concrete noisier and bumpier to drive over, making drivers less happy. It’s why it’s often used for short, low-speed uses like driveways, parking lots, or side streets.

    Just about the only thing concrete has going for it is it’s endurance, which it definitely wins handily.

    Every few years another engineered road solution is conceived - I’ve seen variations that would use glass which could be ‘re-fused’, concepts for recycling plastic waste, and many more. Most of these run into the issue that they’re either less ‘grippy’, or that they simply cost more even accounting for the longer lifespan.
