With version 1.17 nearly finished, and Leoreth's
Plans for DOC 1.18 just posted, I thought that now would be a good time for a dedicated brainstorming thread to develop the 12 (!) new civilizations to be included in version 1.18.
Here's the full list:
And here are the approximate starting eras when they would spawn:
Ancient: Nubian, Assyrian, Hittite
Classical: Vietnam, Kushan, Celt, Toltec
Medieval: Javanese, Malay, Burma, Swahili, Kievan Rus
Early Modern: Sweden
There have been many suggestions and proposals for many of these civ's unique attributes (Unique Buildings, Unique Units, Unique Powers, Unique Historical Victory conditions), but there will almost certainly be changes, given that these civs will be accompanied by a new world map.
In other words, let the brainstorming
begin continue!
EDIT: per Leoreth's
comment, moved Vietnam to a Classical start/spawn
Nice! I want to comment on the inclusion of the Kushans, however.
The main gameplay reason for them seems to be that they straddle India and Central Asia in a time period when there isn't much else to be done there, which is undeniable.
However, from the historical standpoint, the Kushans would only last for some 300 years, and Afghanistan would never again become the seat of a large and lasting empire. Hence, it'd be a pretty short-lived civ.
So, I would argue for including a civ in central India instead of the Kushans, let's call it Deccan for now. Gameplay-wise, it has a similar function of challenging India (as well as the Tamils), but since the Deccan has been the seat of powerful empires almost continuously from ~2nd century BCE till ~18th century AD, it can do so for much longer.
Historically, central India (generally corresponding to modern Maharashtra, northern Karnataka and Telangana) was the heartland of major Indian empires since antiquity: Satavahana, Vakataka, Chalukya, Rashtrakuta, Chalukya again, <intermission due to Delhi eating it all>, Bahmani and Marathas. These empires were all fighting against other major empires located to their north (the India civ) or their south (the Tamil civ) all the time.
Of course, this still leaves Central Asia empty in a time when it most certainly was not [this is unfortunately unavoidable, unless one replaces, say, the Celts or the Kievan Rus, with an antique Central Asian civ (personally, I'd rather not have the Kushans or an Afghanistan civ, but I'm not well-versed enough in Central Asia to offer a good alternative)].
But I think the benefits of a more historical and dynamic India are more important. South Asia was historically disunited with occasional union after all, and North Indian and South Indian empires alike stumbled in the tough Deccan, whose interior birthed formidable empires of its own.
Of course, this means the preexisting India civ will be restricted to being primarily Gangetic... as it should, tbh. After the Guptas, there were a few minor kingdoms it can represent (a brief anti-Hun coalition led by Malwa, the empire of Harsha etc), and then of course the Republic of India in the modern period.
The big problem, of course, is deciding what this Deccan civ should be like. The region is culturally and linguistically diverse (of the empires named above, I think Satavahana was Andhra, Chalukya and Rashtrakuta were Kannada, Bahmani was Persianate and Maratha is self-explanatory). Plus, I'm more a player than a modder, so I must leave concrete design to the capable. Nevertheless, I do think that this civ should be primarily militarily oriented (being situated in a generally less bountiful region, boxed in by two other civs), with maybe a secondary trade aspect (commerce was a somewhat-major thing too: Dakshinapatha, trade on the western coast, the diamond trade etc).
Unique units shouldn't be too difficult: my mind personally goes to Bahmani cannons (seriously, their artillery was kinda insane) and Maratha... Marathas lol.
In terms of UHVs... uh, survive? I jest, but as you have seen, the region has been repeatedly invaded, especially by north Indian empires on their path to subcontinental dominion, and has also repaid the favour as well. I would suggest one UHV be something like to control every city in South Asia at any one time before 1800. Another could be about building some wonders before a certain year, though that's a bit bland as far as UHVs go. Something related to having a stronk military could do as well.
If it's at all possible to implement (and it's totally fine if it isn't), one UHV could perhaps be something like uniting and forming India by 1950.
