You know fishing is a very relaxing part of the game and when you are fishing you get a lot of time to think. I thought wouldn't it be nice to get a bonus when you hit 90 in Terraforming. You could get the ability to change terrain within your tribe area. Maybe at 90 you could get inspired to change terrain to sand, sandstone, dry sandstone, grass, basalt or even.... even your own personal garbage pile if you like that as décor lol. Really it would be nice to be able to do that. Of course it would be tedious. ie. to change a terraform tile to sand you would need something like 100 buckets of sand or something like that. Balalt and entire binfull of basalt stacks, etc. I think it would be fun to be able to enhance tribe lands that way. Just a thought.
