Actually, quite the contrary. Damn good strategy games and decent stories if you ignore the (admittedly very minor and only there if your particular interpretation goes that direction) Darcsen=Japanese implications. It's just that said implications are kinda hilarious and stupid.
WHAT ARE THOSE IMPLICATIONS!?
And what about the Darcsen makes them look like Japanese?
I dunno, I just thought they looked Japanese and, frankly, it is something I could see the game's writers doing considering I've seen stupider shit along those lines in anime. Considering that they, like I said, shoehorned in actual Japanese people in Valkyria Chronicles III, I think there is at least a grain of truth to it.
Or, considering that I can't find anything on a Google search outside of a few people who also thought they looked Japanese, I'm probably just insane and reading things into it that aren't actually there.
