The Saturn had been originally been intended to be a 2D multimedia gaming device. But so many things unfortunately went wrong.
Developers had just got excited about Polygonal Graphics, and Sega realized their next system should have that. The irony is that it was their own Virtua Fighter that got developers excited (not that it was the first, that it was what got attention for polygon graphics). The problem was, the original Saturn design had 3D capabilities that were barely any better than those of the 32X, and the rumoured capabilities up the then-upcoming Sony PlayStation and Nintendo 64 would have left the Saturn eating dirt.
Instead of redesigning the system to make it powerful enough to handle 3D, Sega just slapped on a duplicate CPU and a duplicategraphics card. This is retroactively ironic, because CPUs with multiple cores are the norm in video game consoles and PCs today. But having entirely separate units just upped the cost of the system and the complexity.
While not ironic, the system was also suffering from a legacy of mismanagement from Sega, particularly a lack of communication between the Japanese headquarters and the American headquarters. The Japanese headquarters launched the Saturn without telling the North American branch, so the North American branch created the 32X and got everyone on the bandwagon of that, took their money, and then they were told that the Sega Saturn was being released. The 32X was soon abandoned, which pissed Sega's customers off. Now, the 32X customers didn't trust Sega, which led to all the 32X customers not buying the Saturn.
One really weird mismanagement was Sonic Team hearing that the team developing the Sonic Xtreme was using the engine Sonic Team made for NiGHTS Into Dreams. Sonic Team complained, and the Sonic Xtreme developers had to make their own engine, but that wasn't enough and the game was scrapped. First of all, the creators of Sonic didn't want a developer using their own engine to make a Sonic the Hedgehog game. That's ironic. It's also retroactively ironic, because these days a developer would have to be crazy to stop a game from using a pre-existing engine.
Another odd bit of mismanagement was hiring Bernie Stolar, fresh from being fired by SCEA for his draconian and inconsistent policies, directly into the position of CEO for Sega of America. He then proceeded to start up a "five star game" policy (which basically just allowed him to veto whatever he damn well wanted) and basically took the ax to the Saturn. His policies drove away almost all of the American third party developers, blocked a metric ton of high quality games from being released stateside due to his thinly veiled "no 2D" attitude (ironic, considering that most of the 2D games were miles above the 3D games in terms of presentation and general quality), and downplayed the Saturn as being dead in the water, giving the finger to the relatively small but still sizable fanbase. He ended up getting fired around the launch of the Dreamcast due to completely disregarding Sega's request for pricing the system at $249 instead of $199, as well as completely killing whatever chances it had in the US.
512 KB CD buffer, which helped ensure smooth loading, if not fast loading.
32 KB save memory with the battery backup. A 128 KB or 512 KB memory cart could be added to supplement this.
* While the system was listed as having 200,000 fully-textured polygons per second, barely half could be done in real-time games. That was still an impressive amount for the time.
Unlike virtually every other console ever made, the Saturn used quadrilateral (rectangular) shapes in its 3D rendering, rather than the more traditionally used triangles. While this could theoretically have resulted in graphics far superior to what its competitors offered, quadrilaterals were nothing short of nightmarish to work with in games, even moreso when you considered how hard it was already to create games for the Saturn. Moreover, it made it impossible to do direct ports of games from the Playstation and Nintendo 64.
Overall, the Saturn could potentially have topped the PlayStation in terms of 3D graphics, but the system didn't last long enough to prove one way or the other.
2D was another story, as the system was built initially with 2D in mind, and save for a few effects, the Saturn was a superior 2D device to the PlayStation and Nintendo 64. Too bad it was mainly games in Japan that showed it off, unless it was a CapcomFighting Game or a Neo Geo port.
