As I've never owned a Playstation (apart from PSP and Vita) there's loads of 'important' games I've never played. From the Metal Gear series to Final Fantasy to classics like SotC. This bothered me for a while but I'm over it now. Just don't have the time these days to even attempt to plug the holes in my gaming history.
I technically didn't finish Bloodborne. I was on the last boss, and winning, when there was a power cut and my save got corrupted. Although I started again many times, I never found the time to get to the end. Still my favourite after Dark Souls (which I did finish).
Funnily enough, my import disk of Demon's Souls actually split in two inside the ps3 while I was playing and nearing the end.
I always use a guide for long rpgs as I can't play them myself for fear of missing something important. Think I canned ffxii after it turned out I'd opened a chest I wasn't supposed to and so wasn't able to get an ultimate weapon or something like that.
I once convinced a friend you could turn on the PS3 by hovering your finger above the console power button, but really I was just holding the PS button on the controller under the desk whilst I hovered my finger over the console power button. He tried for ages.
I was cruelly letting my kid believe he could swipe on the tv by hiding the remote control behind my back. That bit me on the arse as he put chocolate all over the screen.
