Also, have you ever added up how much production/commerce/unit support more a 13-size metropolis has compared to a 12-sized city, especially if the tribe has relevant traits?
By the time this becomes relevant, AIs can have surplus gpt available via trading technologies. Especially on Large and Huge maps.
As for the rest, dont you get a little bored always running a city-sized republic? Is that what you ALWAYS do?
No, I don't get bored of it. I only don't run a Republic when I play Always War or more commonly what I call Always Battle (which allows for peace in the middle of a turn, but not at the end of a turn).
If I were turn-rushing a 100k type I would get into Feudalism.
Just build a lot of towns to cover all ground, reach 10 shields per town and sweep down the map with swordsmen
No, that's not comparable. Swordsmen fighting isn't all that efficient. The XOTM games generally have horseman rushes.
OK, the game has been around for some time and a somewhat optimal way of playing has been established, but if you never run lets say...a modern age, communist, no artillery allowed, no trade with those guys, have to research all garbage techs, have to make war with those, (some more self-restriction), (a couple of interesting modifications to the edit), then how dont you get bored doing the same again and again?
The game has different victory conditions and map types. I never run Communist. I also never run no artillery allowed, because I will still capture artillery type units. No trade only applies for strict Always War, but clearly the trading system is there for a reason. The game got designed with it as intended to get used for most games, and I do use it in most of my games. It's not the same again and again with different map types. Also, with different difficulty levels, there exist more variations.
Do you even remember what it is to pause and think if monarchy or map making should be your next tech in this weird situation instead of always rushing to philosophy and trade all the rest?
You mean from not knowing how the game works? No, it's been over 15 years now. Well, I did learn that Map Making after Republic is useful for low level histographic games, even though it's not so useful for fast paced technology games.
But Monarchy over Republic? No, no, no. It's not a question. Only if war weariness is or might be high AND there's no compensation later. Even on Huge Sid, Republic can be better with extreme war weariness, since Republic is better once the war weariness goes away, say for more happy citizens via a more effective use of the luxury slider.
Assuming that you are in need of happy faces because for some reason you cannot trade/claim all or almost all luxuries (happens a lot before navigation in continents), why is the slider a better option?
The luxury slider CAN give a city happy faces. Military police CANNOT do so. It only changes unhappy citizens to content citizens. And happy citizens score 2 points each, while content citizens score 1 point each. If playing for maximum score, thus the luxury slider easily can do better than military police.
And with careful management it is possible to waste nothing, always have your MP exactly where they are needed, while the slider leaves a huge mess.
We are talking over 200 cities eventually on a large map here, assuming we go all the way up to the domination limit. What you say about "waste nothing" won't hold.
Even if you exceed the free unit support, the relevant penalty is a ilussion, you would lose more by using the slider.
0. You're just calculating there. It doesn't really match empirical play experience from competitions, and it makes some incorrect assumptions.
1. You can't research as fast in a Monarchy as in Republic. So, Monarchy is worse for Spaceship, Diplomatic, and 20k games (research is extremely relevant, since one wants to get to technologies with great wonders first to build them).
2. The luxury slider can make happy faces. And those happy faces can exceed three. Military police in a Monarchy has a limit of three citizens. And those citizens only turn content. Happy citizens do more for score than content citizens. So, Republic has serious advantages over Monarchy if going for maximum score, that Republic ends up better.
But hey, you think the standard, old claims about Republic as Monarchy wrong still? By all means submit a COTM, GOTM, or HoF game using Monarchy and see how it compares to the games that use Republic. Most top charting games have used Republic for a longtime, and for very strong reasons.
Republic also fares better than Monarchy if playing for a 100k type game, because research towards Miniaturization, Replaceable Parts, Education, or even just Feudalism goes more quickly under a Republic. But again, Feudalism works out better than both theoretically, if one has a willingness to pop rush buildings with citizens.
