I only owned the 80GB original PS3 back in September 2009 since it catered to my taste the most and by far and as a result i had a lot of my best moments in gaming with it.
The fancy design and features of the console itself like built in Wifi, Blu-Ray, batteries and SIXAXIS along with great 3rd party support especially in the later years and many amazing PS3 exclusives like the Uncharted series, Heavy Rain, Metal Gear Solid 4, God of War series, Heavenly Sward, inFAMOUS series, LittleBigPlanet series, Resistance series, Flower, Journey, The Last of Us, Twisted Metal, Sly Cooper series and Ratchet & Clank Future series.
Resistance trilogy in PSVR with the Aim controller, that would be awesome!
Same for Killzone, Dead Space, Bioshock. Gen 7 has many gems that should easily be able to run in VR next gen.
