I've been thinking this a while now while playing some of the recent commerce games, and it really solidified in my brain when I was perusing the wiki for Commerce.Commerce Overview:
Commerce games stray from just rewarding income to be used for armies the next turn. Instead, you get Gold, which can be spent on either armies or cities.
Gold is further earned by having cities.
The two main commerce settings that vary are the cost per city and the army multiplier penalty. The cost per city is the base cost of gold to place the first city on a territory. Each subsequent city costs +1 more gold, and all cities give +1 gold. Typically, the first army you deploy costs 1 gold, and with a default army multiplier of 10, the first 10 armies will all cost 1 gold each, then the next 10 cost 2 gold each, etc.Local Deployment and Commerce
When you combine these settings, the gold earned from holding a bonus can only be spent either in that bonus, or building a city anywhere. Further, the gold earned from cities translates to anywhere armies.Result:
You can use the gold earned from far-away territories to build cities, and subsequently use that gold to deploy anywhere armies far away from the territories that earned them.Sample Games:
