Poor Vita never really got out of the gate. It looked like a cool little piece of tech, but there was never any game on it that made me go "I better buy that"
There were definitely some hidden gems on the system, though. I loved my Vita. At the time it was my only way to game, besides a laptop I had (and the laptop wasn't powerful enough for anything serious). So the Vita was sort of a godsend for me. Soul Sacrifice is one of those "hidden gems". That was a great game and it boggles my mind it never got released on the PS4.
I also played the absolute heck out of a game called "Ragnarok Odyssey". It ended up releasing on the PS3 later, but it was great fun on the Vita. I have tons of fond memories of that little thing. I agree with everything X-Soldier said, except for one - the back touchscreen. Dear lawd that back touchscreen was awful for replacing standard L2/R2 or L1/R1 triggers.. At least in my opinion. I struggled mightily playing that Killzone game.
As for this game - I've never played it but it looks fun. This was another game showed off in Nintendo's ho-hum direct this evening.
