I think it's worth continuing with the 40s theme.
There are many different games about the future or the Middle Ages, but there were no such games as Termina yet. I really hope there will be more games like Termina in the same setting and timeline. Not the Middle Ages, not the future, not the modern time, but the time of the WWII, give a special aesthetics, especially when combined with esotericism, old and new gods, painting style and mystery. It feels like new sciences have appeared in that world and you are a kind of scientist. I really like this lore.
I loved Termina more than any AAA project, and I assure you that I am not the only one. The painting style is especially unique and beautiful.
But don't think I'm belittling the first F&H. I am still playing it and I love the first part.
I guess I know everyone you were inspired by, but let me ask you, did you take inspiration from the Claymore manga? If not, I highly recommend it.
