The first was that I was -- and still am -- an Amiga fan and a lot of the better Amiga developers seemed to move over to the PlayStation; indeed, the mighty Psygnosis got absorbed into the Sony hive collective a couple of years before the console launched. This is not a bad reason to favour a games platform, but the other is somewhat more embarrassing; I thought the black discs looked cool.
When a wealthy relative gave me a silly amount of money for a birthday gift I took it straight down to HMV on Western Road in Brighton and bought a console, some controllers, a multitap, an Atari arcade collection containing the original Gauntlet, and the brilliant Tekken 2. Maybe I should have put the money aside and saved it for something sensible, but I'm glad I didn't; the PlayStation was a great little console and one that brought me and my friends hours of joy, and a few years later begat one of my favourite games machines ever.
And those black discs still look cool.
