Your reasoning for an Indian update does seem to be driven by conformation bias, as it is largely exaggerated how little the more historic like outcomes are. The rarest thing is to see Europeans in India. Deli regularly dominates, Bahmanis regularly dominates, Mughalls sometimes form, Punjab sometimes exists and survives and expands a little, sikhism usually dies out - at times they even spread. Personally I'd love to see Mughalls dominate fairly often, then explode which then triggers events for europeans to try to invade.
I agree with you except that
1. In reality the Bahmanis didn't dominate, they just died after beating up Vijaynagar.
2. I've played 900 hours and never seen the AI form Mughals, maybe I'm an outlier, dunno.
It just seems like to me that Europe is super historically accurate compared to all the other regions, and while I get that the game is called
europa universalis that still doesn't mean that the focus should
only be Europe, which paradox has also said with it's recent DLC.
And I think that you can also agree with me that the number of events that India gets is on par with regions like Central Africa and the new world, regions that aren't documented very well in comparison.
I also think that you can agree with the fact that Vijaynagar beats Bahmanis more times than Bahmanis beats it, by a large margin. Mostly because of Vijaynagar's large development and because Bhamanis is Shia.
From what I've seen they haven't said where this one will be based. No new mechanics have been shown.
Yeah, I think I heard it's in western europe, haven't really been active on the forums lol.
However I'm not sure you'll make many friends on this forum by asking for a more historical outcome, particularly if you use phrases like "make Delhi collapse". People don't like flavour if it causes historical outcomes without the appropriate in-game causes.
Me being a Eurocentric shitlord my main gripe with India is the anti-Europe trade node configuration and the inabilty of the European AI colonisers to make any sort of headway on the subcontinent.
It just seems like Europe is super historically accurate relative to other regions, Arabia and the near east are also way more accurate now and so is South East Asia, I feel like a region this important (to Europe considering it was a very large colony) needs some attention.
I also strongly agree with your second point, perhaps if more of the trade flowed into Zanzibar.
India always becomes a "Big 3" but who those three are will vary a ton. I've seen it be Orissa, Punjab, and Nepal, and other various strange/atypical combos.
I don't want rigid historical accuracy but I think that the region should at least be historically accurate to the point that the Mughals form and Vijaynagar breaks down, both of these things don't happen a lot of the time. More often than not Vijaynagar eats up Bhamanis and dominated South India and the Deccan, more often than not (in fact pretty much never as far as my games are concerned) the Mughals don't form. Considering that the Mughals and the British were the two powers that Influenced South Asia the most in the time frame of the game I think this is pretty wrong. This would be the equivalent of Scotland almost always eating England and Ireland and becoming the colonial power that England became irl.
That's not true at all. In my games, Bahmanis completely annexed Vijaynagar multiple times, becoming the local blob.
Same here but more often than not Vijaynagar beats Bahmanis because Bahmanis is Shia so it can't get allies easily, and Vijaynagar has more development.
Also both the Vijaynagara empire and the Bahmani sultanate disintegrate irl, I wouldn't mind them living on in my games but I think it should at least be a little historically accurate. In Europe most of the countries are very historically accurate. In the near east, south east asia and arabia it's moderately accurate, but India is just crazy inaccurate. I think that at least the Mughals should form, but that isn't the case 99% of the time. They haven't formed in a single one of my games.
Edit: Also wanted to mention that the reason I'm obsessed with the formation of the Mughals and collapse of VIjaynagar is because these aren't facts you can just brush over, the Mughals are the literally the biggest cultural and historically important empire of the region
and not in a small sense either.
