I still remember the first time I played a couple of Psygnosis games on an Amiga 500: Blood Money, and Shadow of the Beast. Those two blew me away. The sound and the graphics were absolutely stunning for late 80's.

I have a MIST, Vampire board, and still play around with UAE from time-to-time... but there's nothing like seeing the "real" hardware for the first time when you were a teenager. Even with all the hardware I've had over the past 30 years, everything else has felt so incremental.
