Commodore nerd chiming in. Nothing will top going from Commodore 64 to Amiga 500 for me. The graphics, sound quality, floppies, even the smooth mouse pointer movements and workbench, everything felt like a next level upgrade. Specifically have nice early memories from playing F/A-18 Interceptor, Shadow of the Beast, Rick Dangerous, Defender of the Crown, Turrican, It Came from the Desert, Dungeon Master, Cadaver, Gods, Battle Squadron. I still play some of those games today.
SNES was nice too but the start was horrible since going from joystick to dpad made everything awkward. I always held the joystick with the right hand too, the stick, so it wasn’t just a joystick to dpad transition but a right to left hand transition for movement as well. Took awhile to adjust.
Dreamcast was another nice one, Soul Calibur was nuts at the time. Was lovely to finally have PAL60 as standard as well.
