Tempest 2000 is always cited as the Jaguar' s signature game... unfortunately, although it was a great game, that just shows how out of touch with the gaming market Atari was in the era of platformers and fighters.

Started off with the 2600, then vic20, spectrum, and ST. My Amiga lasted me a long time, and until I got my xbox I was pc gaming for a while.

So my hall of shame for non-ownership includes anything by Sega, Nintendo (except GBA or DS I have access to) or Sony.

I missed the Atari' s from the 70' s (Was playing an interton VC4000 instead)
I missed most of the early nintendo' s (Was serving in the forces late 80' s early 90' s).
Played mostly PC games from 95 to 2000(and still do) so missed most of the sega systems (although I am proud to say I did own a Gamegear which I thought was underrated.)
Never bought an original Playstation and missed the Jaguar and Dreamcast debacles.
