In 7 Wonders, you do a lot of building things and purchasing resources from your neighbors. Naturally, you cannot purchase resources that aren't actually there.
However, sometimes you run into a situation where you attempt to build a building that requires a resource that isn't available right now, but it just so happens someone also built the resource that turn.
In such a case, is it possible to purchase the resource from that player?
Times this would happen:
- You were going to build something from your left neighbor, but you have a discount from the one on the right and hey they happened to build it this turn!
- I want to try and build a thing that I can't afford, hoping my neighbor will build something. If not, I'll just discard for cash instead.
