Ok, they're not strictly consoles, but I still have fond memories of my first computers:

The ZX Spectrum (48k):
Fave games were Manic Miner, Exolon, Splat, Jetpac and Saboteur.

The Atari ST:
Head Over Heels, Parasol Stars, Speedball 2, Stunt Car Racer and Personal Nightmare.

And then came the Megadrive and Sonic, and although it flopped badly I really liked the Mega-CD, such great games, Sonic CD, Snatcher, Shining Force... and erm, ok well it wasn't that great, but still worth having.
