To borrow a phrase, the fundamentals of Valkyria Chronicles are strong in spite of its small flaws, and the game manages to convey a feeling of excitement and novelty, quite the achievement in a subgenre mired in the mechanical limbo between Final Fantasy Tactics and X-COM.
Bottom line: Valkyria Chronicles is one of the best tactical RPGs to date.
Recommendation: Hurry up and buy it. It's a great game and a PS3 exclusive to be proud of. Any hatred you have for anime will be offset by your troops' bizarre personality traits and the fact that your loli stepsister is the one driving your battle tank.
