But if you don't build craft buildings early, your opponent will be able to exploit the marketplace for a wide variety of resources (including generally hard to find coal in the early rounds).
Oh, I didn't say differently. I say it's even worse. It's not enough to get the Craft buildings early, it's important to get many buildings at all. If your opponent stops building after getting many Craft symbols, he'll definitely lose - regardless of his number of Craft symbols.
