Y'all may appreciate this new indie game whose development I've been following, where you get to build a subway system based on modern US census data! The dev manually recreated the Apple Maps style in WebGL too. https://www.subwaybuilder.com/

it seems interesting but there's no way to play with it without paying the 30 upfront and I don't even understand what I get for that. is it downloadable? Does it play in the browser?
