District tiles get bonus -underlying tile

[DeckerdJames]

For example, you’ll get something for studying the desert like +5. And it’s like that for all the different tiles and you can adjust them for whatever that makes sense. Maybe the desert is the worst one so it’s lower. I don’t see why that should be because they should all be interesting. So maybe you always get some base amount no matter what the type. And then features just add value so you get something for trees get something for different things. I don’t know. How do you do that but maybe there’s some game rules that could make sense.
