The manual says that Sikhs are both a heresy of Sunni Islam and Hinduism, which is the exact same as in EUIII, and something I thought would be changed. Sikhism is completely and utterly different to Islam (no recognition of Abrahamic prophets or Muhammad for example) so it doesn't make sense as an offshoot of Sunni. And Sikhism is no more an offshoot of Hinduism than Buddhism is.
The Sikh faith is a separate religion in its own right, and would make most sense in EUIII as a late-game religion that emerges through a small reformation-type event in northern India. Just randomly-generated heretic rebels does not make sense for the beginning of the 5th largest world religion, and whilst Sikh imperial power reached its height during the Vicky II era, in the 18th century the Sikh confederacy was still a force to be reckoned with. After the decline of the Mughals, the Afghans tried to move into Punjab to replace them, and the repulsion of the Afghan empire from India was more or less entirely due to the Sikhs. So it's not as if Sikhism is some minor irrelevant sect.
Basically I don't really understand why Sikhism isn't in the game, apart from some heretic rebel names. There's a whole list of reasons:
Gameplay: A reformation-type event chain in India would be cool, it would definitely mix things up. Hindus and Muslims are fighting, the Europeans are poking their noses into things deeper and deeper, and then suddenly a fourth faction shows up who don't really want anything to do with the others. Will they ally with the Europeans to guarantee their independence (as happened historically), or will they join forces with one of the other religions and potentially tip the balance against the colonists?
It might also be unique gameplay-wise to have a chance at playing as a country with very few provinces of its own religion. Even in the 20th century (up until the 1947 genocides) Sikhism never really became the majority religion in any EUIV province, and has always been particularly vulnerable the threat of being assimilated into Hinduism and the threat from Christian missionaries. A very different sort of game from the usual 'conquer province, convert religion, assimilate culture' path you get in Europe.
History: Obviously the Sikh Empire (known in EUIII as Punjab) had Sikhism as its state religion of course. But before that throughout the 18th century there were Sikh states in the Punjab region, who played a crucial role in founding the cities and polities that would become a part of British India later on. These states (the Misls) formed a unique military democracy, a coalition of small republics that would band together to fight off external threats. These threats included first the Mughals (who were mainly a problem before the Misls actually), then the Persians, and finally the Afghans. And there was also Banda Singh Bahadur's uprising in the early 18th century, which was in essence a Sikh-led peasant revolt against the feudal system. Basically, the EUIV time period represents the formative period of one of the most important 19th century actors in India.
Recognisability: Everyone knows about the Sikh religion or at least knows what a Sikh looks like, we are one of the main world religions. In Vicky II the Sikh Empire is one of the larger and more popular unciv countries for people who want a challenge, so it's quite recognisable within Paradox games as well. Paradox has added far less recognisable peoples and cultures into their games before (eg Pechenegs, Nogai Horde, Ulm), so it's not as if this is some sort of obscure thing that will confuse everybody.
In the diaries the developers said that they would be improving India considerably, and I really think Sikhism is a necessary part of making a believable early modern India. It was said that the developers wanted to show the different ways that Hinduism and Islam interacted in the subcontinent interacted, but Sikhism is a really important part of those interactions, and it's a shame that for all intents and purposes the religion doesn't exist. Maybe in EUIV the heretics now work as they did in CK2, functioning as semi-independent religions on their own, which would make sort of sense (but I would still hope for an expansion to flesh it out), but if it is still like EUIII where heretics are just nuisance rebel bands with random names it's quite disappointing.
