I know this is a month old thread but this came up in a google search result and is pretty recent so wanted to throw my two cents in.
There are like 7 60fps 2D games on the 3DO, this is because the 3DO was not made with 2D in mind and has some of the same faults certain computer hardware had around that time, where the architecture wasn't made to manipulate and produce hi-fidelity 2D graphics. It was designed as a 3D machine and an FMV machine.
So the though that there COULD be many 2D 60fps games on the 3DO is completely impossible.
I also would like to point out 3D isn't that good as well. The 3DO's 3D is thought to be great because of still shots in comparison to the Jaguar early on. The 3DO was made with texture mapping in mind and it was easier to do, creating better looking models which works well for screenshots and gifs in some cases.
However, I would like to point out how slow the 3DO's hardware actually was and it's limitations in memory. I can see most 3DO games running on the Jaguar, and in some cases with a significant frame-rate boost, with time and polish.
I however, cannot see the 3DO running many Jaguar games. Iron Soldier 1 and 2, Battle Sphere, etc, are some examples of games with open fields with tons of objects and effects going on like lightning, and with the former, destruction, which the 3DO can't even remotely do without the machine setting itself on fire. Not to mention the Jaguar does all that at a decent FPS.
The 3DO in reality is not only waaaaaaayyy to slow, but way to limited in memory to run games without compromise at 60fps. Heck even in 3D only maybe like 15 are 30fps and some of those have 2D sprites in them. It was good hardware at the time but it's 3D was much more limited than people realize and it's 2D even more so. Samurai Showdown only has 60fps at the stage select screen if I recall. and as

said SF2T has to cut parralax out, though it still does look better than the SNES version imo, it's still a significant weakness if the SNES can retain the parallax.
Ignorance of the 3DO's weaknesses has made people believe that the 3DO is a lot more powerful than it actually is. It can make some good texture models which is why some of the games look great in stills, but while the Jaguar has more blocky polygons, the Jaguar can do more in a 3D space than the 3DO. Some games have lighting and weather change, the 3DO game space would generally remain static and still suffer frame-rate drops.
In 2D games, the Jaguar can do parallax and scaling at high speeds, the 3DO doesn't have the capability to do that. If Atari handled it's launch better with better advertising, and spend more up front on getting game support early, the 3DO would have been dead on arrival. But Atari's missteps gave 3DO an image of an elite class piece of hardware with graphic capabilities that were far ahead. In fact, I would say it's the biggest screw up in gaming history.
