No love for the Philips Videopac?
I've had/got all these and loved them all:
Philips Videopac
Acorn Electron
Commodore 64
Sega Megadrive
Nintendo 64
Playstation 1
Sega Dreamcast
Playstation 2
Nintendo Gamecube
XBOX 360
Playstation 3
Nintendo Wii
Nintendo WiiU
Badass Gaming PC
Nintendo Switch
I think the biggest "whoa" moment for me was seeing Sonic the Hedgehog on the Megadrive. The graphics, the colour, the speed of movement, the gameplay, the music, the crispness of the audio, it was a jaw-dropping moment that stayed with me. I think in terms of giant leaps, that for me was the biggest one. Goldeneye on the N64 and Metroid Prime on the Gamecube were other moments that lingered long in the memory, also Wipeout on the Playstation 1.
Overall though, I'd give it to the XBOX360. I think the X360 and the PS3 were the golden era of gaming. The catalogues for those systems are the deepest and best of all time. You could buy either as a second hand console right now and enjoy an incredible variety of titles for an absolute pittance. I loved both, but without wishing to start the console equivalent of Ronaldo vs Messi I'd give it to the 360 as cross-platform games generally ran better on it.
