Maybe its just me, but it seems like in BTS I tend to start off in heavily forested areas (I play primarily on "Big and Small). The problem is that I can never find a potential site for a city that has anywhere near as many nearby forest tiles as my original city started off with. So... should I leave the forests alone for a future National Park? Should I make a worker and research bronze working first thing so I can fuel an early game explosion? Should I wait until mathematics and THEN chop?
