Unless you know something i dont, ps+ is offering Uncharted, Gravity Rush and Whipeout plus some psn games, non of these is a ps1 game. And you get all this plus more to come for 50$, if this isn't a selling point i dont know what is.
I don't know.
I read a lot about PS1 classics so I figured it was a part of PS+. Everyone seems to be using PS1 and PSP games as selling points, and I would rather have Vita games to play primarily.
This isn't to say Vita doesn't have good games. Alot of people seem to be enjoying their Vita games. But there's certainly nothing there with mass appeal to push the system to the masses. So it'll ultimately remain niche (unless that changes, which I don't see happening).
