So does that mean, for instance, the Huns would not see bonuses to cavalry during the Classical Era, but after? Or does the Legacy Trait take effect as soon as you adopt the culture? I meant more from a historical perspective than a gameplay one. From a gameplay perspective I don't think I've ever seen it before and I think its pretty clever. But what would be the historical equivalent of going industry mode, or going science mode? Literally just changing the names could be enough, and since its still in alpha I'm not worried. But I think it would be more interesting if "industry mode" were instead something like public works funding, euergatism, or wartime production, with associated mechanics and limitations, like having it limited to using production on buildings vs units or something. Or maybe "science mode" could be something like technological revolution or research investments, where a new tech can boost FIM or something. On the other hand, simple is always better, and having a straightforward, fun-to-play design trumps historical nuance. But I think a few minor modifications, even as small as picking a different name, could give it a more creative design from a historical perspective.
