This discussion is no longer benevolent. Calling a civ OP out of the blue without defining the kind of gameplay you want is not relevant.
On the paper Norway or Russia are not scientific civs so you could say that they are not OP for science games but in facts, some people can do great things with them. The facts make a civ OP and not the civ itself.
civtrader on Redit won a religious game with Genghis on turn T76 but you could say that Genghis is not OP for religious games. The facts show the opposite. The point is that a lot of other factors such as the map's RNG, the city states, natural wonders can change a game. A less-good civ on the paper can beat an OP one due to these parameters.
Indonesia can compete very well on cultural games if your map alow you to spam your UI. If you have colossal heads and moaïs in your game then any civ can compete well on cultural victory by spamming improvements.
I think we should considere a game as OP, including all the parameters ant not the civ itself because in facts the map makes the game OP more than the civ itself. Hungary can be OP on some maps but if you have no rivers it will be quite the opposite.
@Manol0 To be honest a lot of other civs can have fields cannons and cuirassiers by turn 130 with a good science.What you mean is more having this without having a good science ? Once I had 300+ culture by turn 100 with Pericles so it is way OP and need to be nerfed ? Probably not, things are more complicated.
You cannot way that having field cannons by turn 130 is OP without a comparison with other civs. Having fields cannons with Babylon by turn 130 is OP only if no other civs can have it even with a beautiful maps and a lot of science. To be honest it is not that quick.
ou cannot call Babylon OP without a comparison. If you search on this civfanatics community posts and on reddit you will see much more interesting things than having field cannons by turn 130.
Can you give me the file at turn 1 if you have ?
