Like twice the size of the campaign map "Gathering of Heroes" Eurupe 1939. It's a good map but if you know how to play, It won't take you very long to steam roll the enemies. It's only a challenge when you put on the special factions on but there more of an annoyance. It REALLY irritates me when these fuckers just randomly "SNEAK" into your castle and rob you of one of your vassals, especially your wife and/or children. It maddens me even further if they have really good stats. My wife got kidnaped and raped even though her states were past 120 >_> I'd rather just have more "regular" factions than these annoying ass factions. It's defeat obviously if you lose/get captured. Maybe a Mongolian invasion like faction or some "holy" faction that wants to kill everything that not part of their religion.
In fairness I think actual grand strategy scope is a bit beyond the games capabilities to render, given that paradox interactives games are probably the best known examples of the genre I'll use them to give a sense of scale; the smallest scale for one of these games is Stellaris on a tiny galaxy size (200 stars), meanwhile games like Crusader Kings 3 has over 2500 counties and Europa Universalis 4 has 3137 provinces. As far as I am aware TohoK has under one hundred cities as its default game map so it would take a significant expansion to get close to even the lowest number.
If you feel like giving it a go that's fine, just be aware of the sheer scale of a project you would be taking on in the attempt.
I didn't mean REAL grand strategy maps, just a map that would fit that "idea" of a map for this game, not a literal grand strategy map from CK II in this. That being said, alot of CK stuff would be great for this game. I feel like two hundred, MAYBE three hundred cities would be good for the "ultimate" map so to say. I do have the map editor but I have literally no idea how to use it really since there's no tutorial to my knowledge lol As for names, I don't think it really matters does it? It's not as If any of the territories have any disguisable traits, there all the same but have different names. I personally wouldn't care if they were named like A1, A2, B5 etc. If the map becomes too hard to read, couldn't just break up the map into other windows you could access like with anything else?
As for other things that would be nice, You should be able to give the tittle of "wife" and "Concubine" in the editor menu. In NG, characters lose these tittles and they can't get them back If you decided to not keep their stats from the prior game and you can't edit the stats in the debug/editor screen either to have them unlocked for that character. Trust me, I've tried lol . I know it's a minor thing but it's sorta annoying.
As for adding things, the tittle of Oath Brother/Sister from the fate era game would be nice as a alternate to the romance title
A basic bloodline mechanic would be nice in like CK where a child born of your dynasty may be able to increase a specific stat faster. It be nice if the game acknowledged your dynasty as well rather than your family just being considered "another" character.
It be nice too if you could wed kids to another country for diplomatic options though, I suppose that really wouldn't work since males don't really exist in this game and even when they do, they don't get into relationships or become evil and do horrible things unless there in the special factions.
