Yeah, the problem is that you need PS4, Vita, game, and good internet connection to play it on the go. I'm playing it in my home with the vita directly linked to the PS4, but I wouldn't be able to play well the moment I step out of my house. I don't take my vita anywhere though, so it makes no real difference for me. Some of the people complaining are complaining because they don't have a PS4 and don't want to shell out the money for one when they already have a Vita.

The price point thing is just that people think a PSP port (their words) shouldn't cost the same as a full price PS4 game despite the fact that a good bit of work was done on the remaster, and it is already a content rich game. But people like to complain on the internet no matter what.
