If you haven't subscribed to PS+ and got them free, or are late to the Vita party, then you could have missed out on some of Sony's finest games for the handheld. You can right that wrong, relatively cheaply, in the latest Sony sale on PSN, that throws its big-name games into the bargain bin. The PS3 titles in these series are also getting a chop, so you can catch up on some gaming history too.
And if you have just subscribed to PS+, there's an extra 10% off too, although I think most of the games are still on the free list, could be Sony confusing itself, or the games will no longer be free when the service updates, so sign up quick if you want them.
