In 2007, Xbox 360 owners received a few games which PS3 only gamers were not invited to. Two them included 2K Games’ BioShock and Namco Bandai’s Eternal Sonata. A year later, those two games are no longer exclusive. I’ve already taken a look at BioShock’s PS3 demo and now it’s Eternal Sonata’s turn. Will the PS3 demo finally convince me to pick up this JRPG?
