Spoiler :
Not really imo.
Many cities like Castille for example weren't even self-sufficient in food, they became population centres for political reasons.
Of course we can't replicate imports in this manner in CivIV, at least not that I know of. I would be cool to play as British and have London harvest food tiles on the other side of the world at a penalty. Perhaps it could be a Capital only thing... akh, what am I saying.
Even then, political usually either meant "defensible" or "central" - and most likely full of vulnerable rural areas feeding The City In Question from the CIV equivalent of its second ring, if nothing else. While I'm sure there are a couple exceptions, I'd argue this is necessarily true before the advent of Refrigeration.
To be fair, this is less of a problem for RFC/DOC than for RFCE, except maybe in Russia and the US. (Especially Alaska, not that any one but He-Who-Must-Always-Play-On-Marathon would ever care. (a.k.a. This guy))
Spoiler :
I get your idea said:own [/U]cities sounds well... a bit funny.
More simply, a later spawned Russia would simply raze independent Novgorod rather than flipping it. Also, though your suggestion makes sense, the current stability mechanics make this unusable.
Stability mechanics should have that liberating or razing your Cities cause no penalty.
Razing own cities/flipped cities is something I feel no compunction against using World Builder for. Because screw you, Jacksonville/Lyon/Ankara! Would be nice for that not to be cheating (if only on the flip, by adding the "has revolted keep/disband" button) but that might be annoying to code?
edit: Founding 1s of London actually makes so much gameplay sense...[/QUOTE said:Il faut agacer les Parisiennes. And while the Moors are ruining my Pamplona-Madrid(1S)-Cadiz Power-I, I still get to build Metz and raze Frankfurt as the French. And this newfangled Polish thinga-ma-bobber being there to clean up the mess makes me happy.
