It's not exactly that I'm sad the game isnt exclusive, as I said, I'm sure it's great for GR in particular as it'll have a better chance to widen the possibilities of the game and the audience of course. I'm just sad for the Vita. I think exclusives are it's best shots at increasing the userbase, and it's losing all of them one by one. Increasing the userbase means it can push more developers to make something exclusively for it, meaning we can get more game's pushing the limits of what the Vita can do, which sadly it feels very few games have actually done. I can't see indies pushing the Vita userbase since they're usually on consoles and PC too, though some will value that they can play such games portably and perhaps buy it for that reason. Remote play possibly being the other.
For the record too I actually own both a PS4/Vita, possible I will double dip on PS4 too depending how it is and how it's priced and etc., just fed up of Vita losing all of it's "hooks" to get people to actually buy one.
