I love my Vita too but I won't buy anything for it unless its a sale. Almost everything I have is from PS+.
I want to buy the games in physical form so I have them. The plug & play aspect is still the biggest plus on a console for me. So I want to buy as many Vita games in phyiscal form as possible, even though I rarely play with it at the moment. But I'll be damned if I'll pay 40€ for a game that I mostly buy so show some love for the console. But I want to get those Vita games before they are oop. Getting Danganronpa was already a bit of a hassle, actually. But at least I can buy them now for 30$ or less.
