I actually enjoyed the game's aesthetics on the basis that I saw it as reverse Orientalist. Let's just mash WWI and WWII together, ignore how they're each historically regarded and use a tone that is completely off, and just pick and choose whatever aesthetics we think look cool and plop whatever story we feel like into it. I genuinely don't think there's any deeper meaning to the bad guys being geographically Russian because that would require closer attention and faithfulness to the setting than anything else about the game indicates.
If you wanna say that Orientalism is still bad when directed towards Europe, that's totally valid and fair, and my take is probably bad from an objective standpoint, however, I just personally enjoyed seeing a perspective capable of treating it that way. The concept of "WWI but with the tone of Fire Emblem" is just so alien that my curiosity overrides my sense of it being inappropriate.
