Question around colonies

[lummoxybez]

Do I need to build a road on the resource tile before I build a colony there, or does the colony come with a road?

 

[Bartleby]

You don't need to build a road.

If you build a colony or a town on an unroaded square, next to a roaded square, the road will connect up. Same with RR instead of road.

This rule can be quite helpful on tiles that take a while to road like jungle or marsh if you are in need of it immediately.

 

[WeirdoJoker]

It's very helpful for strategic/luxury resources (whether colony or town), but what about bonus resources? And is it ever worth building a town ON a bonus resource? I don't, because then I cannot improve the square (i.e., irrigate or mine) and get more out of it.

You get the commerce, so founding a town on a commerce bonus can be helpful sometimes - I'd found a town on tobacco, for example. I might found a town on a gold hill if food is in short supply, so that I thought I wouldn't be able to work the hill otherwise.

Building towns on strategic and luxury resources also makes it much harder for the AI to disconnect them in wartime.

And is it ever worth building a town ON a bonus resource?

It depends on food. Many bonus resource increase food. The food output of the city tile does not depend on the tile including the resource. This makes founding on on bonus resources wasteful. If reasonable possibly you should found towns on tiles with low food like desert or plains.

Shields and commerce are fully utilized by cities and metropolises.
