So I guess it's just for the "European region" or it would probably say so.
Big Sky Infinity will be free for Euro PS+ but not for US. :(
Going by past experiences EU PS+ also go other free games on release day like Hell Yeah! Rabbit + Machinarium, while US got PS+ discounts or nothing, so I never even had my hopes up.
