The last time I played mine was when Hotline Miami 2 launched. I was having a great time and unfortunately, my cat knocked it off a shelf and the screen shattered. Haven’t fixed it and have never played a Vita ever since.
For me it was just yesterday. Granted, I was only using it to remote play Destiny 2 and squeeze in a little extra Iron Banner time while the kids were napping, but that counts, right?
A week ago. I have acually been using it a lot for Remote Play, as it's easier to play around the house with the Vita.
I sold my Vita about a year ago, about when the vast majority of the games I liked for the system got PS4 ports. Last time I remember playing it was October 2016 when I lost power for half a week due to a hurricane. I still have a PSTV and my old memory stick somewhere, but I haven't had much reason to pull it out and set it up... eventually the visual novels I want make it to PS4 or Steam, and my backlog is big enough without adding another platform to play in the mix!
The last time I played my Vita was when I Platinumed Bad Apple Wars, which I got for review. That was September I think.
I use my Vita quite often for remote play. The wife recently had surgery and was stuck at home with me for 6 weeks, so in order to not drive her crazy with all of the games I've played, I'd let her watch TV while I sat with her on the couch and played on the Vita. Happy wife, happy life.
It's been a long time — too long, perhaps. Severed was the last time I picked up a Vita game at launch, and it's going on 12 months since I even turned the damn thing on. *Cue sad music*
I honestly don't remember. I think over two years ago.
