A question on Rhodes and other very small lands

[Titus Livius]

I generally play as the Greeks, but whoever I play I am extremely fond of taking every island in the Mediterranean. Rhodes is possibly the best of these.

After having built everything possible in Rhodes, the only option left was to build roads. My question is this: is it even worth it? Rhodes is basically a postage stamp and I don't see that building roads would do any good at all. I have the same concern with other territories like Crete, Sparta and Corinth. Should I build roads, or would that be throwing my money away?

[HoreTore]

They increase trade, so yes, it is a good thing to build.

[lars573]

The boon to trade that roads give even on a postage stamp like Rhodos is totally worth it.

[m4rt14n]

roads only increas land based trades, so no.

[Byzantine Prince]

Technically the goods have to be transported to the Docks so yes you'll need roads to maximize that.
