Allow me to introduce myself. I am Hexachlorophene J. Goodfortune, Kidnapper-At-Large, and Devourer of Tortoises par Excellence, at your service.
If you can read this, then this sentence is false.
I have two questions.
1. If I am the Indians can I use any hut or village tile I own as any resource? For example can I use the free level 1 tech hut token as any resource?
The Indians can only spend resources as other resources (and only as market resources, they don't get unlimited spies and uranium).
2. With the expansion came the possibility of stealing/destroying/spending, yours and other player's coins. Am I right in thinking that you can only perform these "coin abilities" with coins obtained from technology cards and/or village markers?
Yes, there has to be a physical coin token to steal or remove.
