PROS:
Interesting story and characters
Great voice-acting (if a bit anime-esque)
CONS:
Gameplay is shallow compared to the main Valkyria series, and gets boring after a while. Feels more like Koei's "Warriors" series (hack n' slash)
Cutscenes are long, drawn out and not very dynamic (wasn't a huge problem for me, but just be aware of it)
Apart from a similar setting, very little in common with Valkyria Chronicles
Long length, but doesn't feel like it needs to be that long (a SLOG)
