My thoughts on current state of game

[Chaingun]

Why isn't the game suited for the Napoleonic wars? I agree that is not suited for the massive industrialisation era, but the Napoleonic wars are the cherry on the EU4 era cake, they are basically the natural direction in which every EU4 game goes, to a lategame slugfest between a few majors and big alliance blocks across Europe. For this, at least, the game is realistic.

I did try to add AI behavior for that in the late game related to the great power feature (and to emulate human end game wars from MP) to 1.18, but couldn't complete it in time (that's why there were "great power frenzy" defines). My reasoning went: AI blobs are often much too docile late game after having accomplished their territorial goals and being evenly matched with each others. Human players would on the other hand try to cut each other down and therefore be much more aggressive with highly dynamic results - so I tried to make it like that with nations trying to climb on great power ranking, with the added requirement huge wars should be somewhat balanced. What happened in that implementation was an unending series of pointless 1v1s because of lack of synchronized war declarations and lack of use of imperialism CB, so countries would make strange seemingly suicidal 1v1 wars without any territorial transfers.

AI work on stuff that does not pay bills and that leads to behavior not all players necessarily want (especially if not very well implemented) tends not to be very popular though in terms of prioritization for obvious reasons, but @Gnivom could pick up on it should he ever have some spare time to deal with this topic. To be fair I think it could be better done too with GUI/gameplay support as having too much implicit AI behavior might be opaque and confusing to player.

To get them to form or have their cores show up, requires Mughals to be formed and own atleast one core on a Maratha culture province between 1660 and 1680.

This isn't how it works at all there's more than one Maratha event and last I looked wiki hasn't been updated in years for them.
The only real requirement is that their home region is controlled by a sultanate when the right days rolls around.
Marathas are a revolter nation which is the biggest reason they rarely show. Empires in eu4 are a lot more stable than in real life and in real life their rise (as well as the rise of the EIC for that matter) had a lot to do with the shattering of the Mughal empire.
India is always on my mind though so you may see something more for the Marathas in the future at some point

Great Britain did and they have 0 events too

Huh?

Edit: Are you saying you think we should restrict the British events so you can't get them unless you form gbr? Great Britain have more events than most countries in the game but you can get them all as England too (Scotland couldn't unless they form GBR though).
