Probably overthinking a goofy anime game franchise but I find it interesting that they'd choose to combine Germany and Russia into one aggressor nation for their WWII facsimile 
I can't really call it liberal anti-communist brainworms though since the East Europan Imperial Alliance is more reminiscent of Imperial Germany than anything and I think the devs were consciously avoiding depicting anything even close to fascism or communism because Sega didn't want their wholesome anime WWII game to be political

That didn't stop them from writing in a distrusted and hated minority that was sort of a stand-in for Jews though
I was looking for PSP games to check out and remembered Valkyria Chronicles went PSP exclusive after the first game. I played the first Valkyria Chronicles when it was released on PC a while back and while I enjoyed the turn-based tactical gameplay I sort of hated the game's aesthetics. I'm sorry, but I can't take your story about the horrors of war seriously when it's depicted in bright pastel colours and when everyone involved looks like a Pokemon trainer. Plucky child soldiers is also one of my most hated anime tropes
I like the game but holy hell does it have major major issues. There's a few maps from mid to late game that I had to redo on my first play just because of mid battle events that happen after one of your guys crosses some invisible map line that activates reinforcements or some plot weapon or whatever and makes it hard to use your scouts as scouts. Almost a really great game that is just a good game due to some minor stuff that adds up. Also has a bit of the fire emblem problem where some unit types are just better.
If I recall correctly scouts were absurdly overpowered because flanking is absurdly powerful so just having tonnes of scouts and rushing the fuck out of everything worked amazingly.
