I have one, still hooked up. And I play it from time to time. I have 23 games for it, plus 12 for the Jaguar CD.
I bought one close to "launch" back in 1994. I was in the Army and had just been moved to Maryland, and hadn't seen one for sale before that. I bought it because the Aliens vs. Predator game looked killer in the game magazines, and the store clerk assured me it was shipping to arrive the next week. LOL. Not even close, it arrived months later.
Nevertheless, I had plenty of fun with it. It did its job, giving me a taste of the next generation, before that generation really arrived. It had a few highlights, like Tempest 2000 (the game in my avatar), Iron Soldier, Aliens vs Predator of course, and even Cybermorph I found really engaging. Watch AVGN's Jaguar video for hilarious impressions of Attack of the Mutant Penguins - a very fun game. And it has a unique, very awesome version of Wolfenstein, and by far the best version of Doom vs. the 32X and 3DO - those ports are shit. The Jaguar's is ace.
It's a train wreck of a console, though, just horrible. 64-bits, ha, sure. Give the Jaguar credit for making people stop thinking bits matter, perhaps. It's clearly more powerful than the SNES and Genesis, and even the 3DO, but it's not even close to the following year's Playstation and Saturn. Even if Atari had the money to hang around, it could never have competed.
And the controller, while perfectly comfortable and functional (despite what it looks like), was archaic even then. No shoulder buttons, years after the SNES? And 3 face buttons, years after the Genesis tried to patch up that same shortcoming? Unthinkably stupid.
It was a transitional machine, along with the 3DO, and 32X I suppose (I still have those also), and like those systems, not much of its library has aged very well. A lot of it looked dated or didn't live up to its promise even at that time. They were all quickly forgotten as the first impressions of the new consoles arrived. I couldn't wait to get my hands on the Saturn and Playstation. And they quickly delivered on the promises the stopgap consoles could not.
Fun fact: the Jaguar CD, which I got much later, actually launched AFTER the Saturn and Playstation. Isn't that bonkers?
