Indeed, as per the two post above, Switzerland might make for a great "by my own rules" Civ like Venice, with banned military expansion (Neutrality), while still being able to use military for defense or to support allies without territorial benefit - altough maybe other forms (mercenaries). And with reinforced bonuses for diplomacy and "cultural" and "religious" war.
Much like venice was banned from "exploration" expansion to focus in military and economic war.
I'd rather have these uncinventional civs as DLC instead of x-pac content, however (make more sense as extra tweaks of the game, an it woluld be also easier to "ban" them if you want a more standard game.
Venice was not in a DLC and I doubt that a lot of players were complaining when they see Venice as an AI in the game.
And, as Siptah said, it'll be amazing to see a civ unable to declare war. A "by-my-own-rules" as you said. With, maybe, a penalty for civ attacking Switzerland (maybe, each time a nation attack Switzerland, an emergency is automatically created, or whatever/however the system of emergency works), as the war weariness being superior for civs attacking Gandhi.
Some people say that Switzerland is not a good candidate to be a major civ in Civilization because they are not very influential. But, by my little europeanish point of view, they are as influent, if not more, than Australia (already a major civ) or Canada (a strong candidate). They were the core of Europe, there mercenaries participate in almost all, wars, they were the siege of the Society of Nations, they are the siege of the International Postal Organization... In the collectif mind, Switzerland is an archetype, a symbol of neutrality, greed and democracy. Plus, they are a really unique system (government, culture...), and they will be a unique civ to play and, probably, one of the funniest.
ONE A SIDE NOTE
Is it me, or there is no Italian city-State in the vanilla game ? For me, it's pretty peculiar. Think about it : the vast majority of city-states who had a strong influence on their neighbors were, for a large part, italians : Venice, Genoa, Ancona, Amalfi, pisa (mercantile), Vatican City (religious), Florence, Milan (cultural), Bologna (scientific, because of their incredible university)... The only I can't think about is industrial and militaristic but because it's not the part that interest me the most in Italy History.
For me, the fact that there is not a single italian city-state in the vanilla game is a
STRONG HINT about Italy being a major Civ. Perhaps not in R&F but in the next. I bet my Forbidden City on it.
(plus, it bugged me that in Vanilla game city-State represent minor civ and not
real city-state/little state. I loved Monaco, Singapour and all... But Seoul represent just Korea, Amsterdam Netherlands, and even Jakarta was representing Indonesia. I preferred civ 5 where city-states were really city-states
Rhaaa ! Absolution just say it before me !).
