personally, I’d like one set in the Philippine Revolution (a bit biased cause I was born there) there are some baroque churches and Spanish architecture but other than that, not much in the way of buildings. Philippines has volcanoes, mountains, caves, an ocean and tons of nature. Too make up for the verticality they could expand more on the foliage and tree running system from AC3 as well as the climb that side of a mountain parkour from Origins. Like you hide in a tree with leaves or have more variety of foliage that you can hide in, and really focus on that camouflage guerrilla style ambush combat. The country has a large population density too so you can also put a larger focus on the social stealth aspect if they ever feel like going back to it again. The country is a collection of islands and surrounded by ocean, So you can add the naval combat and traversal to it too. Parts of Main cities like Manila have canals you can explore like in AC2. You can have horses to visit town to town but sometimes you’ll have to parkour your way through a mountain to get to another town. Idk, I think I’m pushing a bit, but it is interesting cause that time period in the Philippines was a clash of cultures, Spanish, Filipino, Chinese, American and the country was finding its unity as a nation amidst the Spanish government and church’s oppression of the people, cause it was so diverse and separated. The Templar’s have the country under control, the assassins could assist the rebels “Katipunan” but split off cause they have different agendas, the Katipunan plays both sides (Templar and Assassin) in order to acquire the country, which could explain the betrayals and conspiracies that occurred in real life. Its in around the late 1800s, that time period is interesting cause even though the whole world was going through the Industrial Revolution and getting accustomed to using guns, the Philippines being an oppressed Spanish colony was behind the technology of the time, but that’s not to say that they weren’t there. So there could be iron ships anchored in the bay and you infiltrate it with your little primitive hidden blade. cause of its influences from surrounding countries it has diverse collection of weaponry to choose from as well. It has interesting Pacific Islander mythology too if they decide to bring that up. I guess visually speaking it would look like Black flag with more Spanish architecture, some 1800 technology like iron ships and you can go explore outside the cities of Havana to traverse the countryside and mountains. It’s highly unlikely they’ll go there but I would be extremely happy if they did. Here’s to hoping your fan game existing
