I've notched up Culture, Science and Economic victories playing Deity but haven't come close to a Military Deity victory in Modern yet. Can anyone share any insight into how they've done it please?
Leader/Civs?
Number of opponents/which ones?
Map type and size?
What you did in the earlier ages to prepare for Modern? Did you follow the Military legacy path in Antiquity/Exploration or is it better to do different things to best prepare?
Tactics for Modern?
Thanks in advance for any help offered!
Basic gameplan for Modern age military victory is very simple: Rush an ideology (fascism is probably best) and then go an conquer 10 settlements. Don't bother waiting for the AI to pick up an ideology: It might delay you too much and even in the best case, it is just 3 settlements less you need to conquer.
In Antiquity, try to get at least two points for the military path and get Fealty. You really want to push your city limit over the game, so you don't have to worry about it too much during Modern. Other than that, especially in Exploration, build or conquer a good economy and build army commanders and naval commanders and fill them with troops/ships. Fight wars to farm XP for your commanders to level up. Take cities to cripple your enemies and bolster your own economy, but leave weak towns alive, so you can easily conquer them in Modern.
If you are struggling, you can rush flight and buy squadron commanders full of bombers. The AI cannot really answer that (put a land unit on them, though, the AI can get lucky, otherwise). Also, use your navy. Towns on small islands are hard to fortify and make easy targets for your fleets and give you the same points as a fortified city, which you might need to siege for 10 turns.
Maps don't make too much of a difference. Maps with many little islands might be easier if you can conquer all the fishing towns the AI loves to build on them.
Civs are also not that relevant. There are some bonuses that can help for them, but none of them are so strong that they massively help you. When in doubt, Prussia or Japan are good choices.
Leaders: Most militaristic leaders will do. I think Tecumseh is the strongest if you can nab a lot of city states. For the opponents: Peaceful leaders are obviously easier to conquer, and you probably want to avoid Tubman. But other than that, I don't think it matters too much.
