Valkyria Chronicles isn’t just a brilliant game, it’s a brilliant Sega game. That means something. Contemporary Sega is a multi-headed beast, doomed to forever bear the wound of its exit from the hardware market, capable of both atrocities (the recent Sonic Boom) and beauties like this. But it has until now, with the honorable exception of publishing the Total War and Football Manager series, never really been a PC developer so much as a PC porter of ambiguous distinction. Valkyria Chronicles suggests that Sega, finally, is bringing its ‘A’ game to the most important platform on the planet.
