Yes, I have some interest in the Russian and Spanish civil wars, and early China conflicts.
I may not buy any of it, but still find it interesting.
I'd suspect that MMP would tend to shy away from subjects already well represented by a TPP, but who knows, if they figure it will sell
enough it's worth the effort.
Honestly, with all that's already available I'd have a very hard time trying to fit in more.
My favorite subject is really WWI, but tactically it's a mess, strategically it can be pretty stale.
Operationally it offers quite a bit of interest, I have Breakthrough Cambrai from MMP and it's good.
More like that would be cool, but that's not ASL.
