To clarify, there is taxation in this game. It is based entirely on your population number (which is kept hidden from you). You will automatically receive it in your T1 results. If you want more Gold, ask for it. It always goes well when you tax the hell out of your people! (For the GM to have fun
)Taxation can also be obtained from trade going into and out of your nation. Open borders and generation of goods that aren’t generic resources are good for this.
