Multiple tiers of tiles

[Sasza22]

Tiles increase movement speed, higher tier tiles increase it more. Why not improve upon this? Standard tiles give 25%, metal give 50% iirc. Standard ones are basically free, you can construct it out of any rock. Metal are pretty hard to get early and you don`t want everything metal beacause of heat conduction.

My idea is to introduce refined tiles that could be made out of ceramic or another element - concrete, that would be created in the rock crusher out of sand and water. This type of tiles would give 50% movement speed.

Then there would be a nex tier: advanced tiles with 75% extra move speed. Those would require 2 types of resources to make. Like plastic and glass for fiberglass tiles. This would add more uses for both plastic and glass that don`t get much use after you get your solar panels and transit tube system done. Filling the high traffic zones with those would use some of those.

Finally an end game tier: speed tiles doubling your movement speed. As end game should be you`d need sme space materials for that. Maybe visco gel and steel. They could have a nice futuristic metallic look with some purple veins.

This would giive a nice feeling of progress and improvement to our base interior.
