I got my Jaguar back at launch. I've accumulated a sizable library of games for it--about 80% of the official cartridge games, and all of the CD games. While there weren't very many games produced for the system, it actually has a fair number of fun and enjoyable games.
The system often gets a bum rap, but I think a lot of that is due to the following:
1. The release schedule was plagued with empty promises, frequent delays, and cancellations. This was especially harsh in the system's first full year on the market, in which only 10 games were released. Yes, ten games spread out over one full year. That's not even one game per month. While there were some absolute gems among those ten games (Tempest 2000, Alien vs. Predator, Wolfenstein 3D, Doom), the waiting game was horrible. Sometimes two or three months would pass before the next game came out. Lots of people lost confidence in the system during that time.
2. When some of the long-delayed games finally did make it to shelves, they turned out to be very disappointing. Some good examples are Checkered Flag, Club Drive, and Kasumi Ninja. None of these were in the initial ten, but they came out shortly afterward, in time for the 1994 holiday shopping season. All were hyped up, all were delayed for many months, and all were great letdowns. This was a tough period for Jaguar fans when the 3DO on the other side of the aisle was getting games like Super Street Fighter II Turbo and The Need for Speed right about the same time.
3. Atari's persistent tendency on emphasizing "64-bit" in their advertising for way too long, particularly after the 32-bit Saturn and the 32-bit PlayStation were released. That marketing tactic might've been cool at the time the system launched, but from mid '95 onward, they could (and should) have ceded the "power" angle, and just focused on promoting some of their better games. Instead, they insisted on ads that heavily pushed "64-bit" over "32-bit", which invited people to make comparisons with the Saturn and PlayStation.
If you're willing to look beyond these blunders, you might find that there's still some fun times to be had in the Jaguar game library. While some of its most prominent hits are available in better versions elsewhere (especially true now, more than two decades later), there are also some great games for which the Jaguar version is the best or only version available.
