This is obviously a question just for fun
but it came to my mind because I came back to retrogamer.net looking for games suggestions and I did not find any links to PS3 games in the sticky "best games for X" thread.(some irrelevant background story follows...)
Incidentally, this is also my first console ever, since I've always been a fan of computers rather than consoles (not counting handhelds which I consider their own category). We don't even have a TV at home, so we play the PS3 exclusively on a projector. We thought for a while about buying a PS4 for our kids, but went for the much cheaper second-hand PS3 option mainly because our friends wanted to get rid of it. Of course my kids now get the bad remarks at school "but the PS3 is older than you..." Nevertheless it is still a HUGE step forward in terms of gaming experience compared to our typical 80s-90s retrogaming habits
particularly because of the few additional controllers we got with it i.e. the Rock Band fake instruments and the driving wheel/pedals. I will never stop gaming with the C=64 or the ZX Spectrum or the Amiga500, but I think these new options complement our gaming habits nicely 
For me, retrogaming interests started in the early 2000s with MAME and C64. At that time, I had no interest whatsoever in bringing down my old Amiga500 from the attic, it was way too recent. Only around 2010 or so I started to gradually take other systems back, Amiga itself as well as Spectrum, DOS and MSX. Only in the last couple of years I've taken out my old Windows games such as early Blizzard titles and the "XYZ Tycoon" or "Sim XYZ" series. So yeah it looks like 20 is more likely for me
