Saturn? Good console.
It had alot of good conversions of fighting games, that I wish were on the dreamcast, that also felt like you were playing the arcade version, like X-men vs. SF, Marvel Superheroes vs. SF and Vampire Hunter etc. Lots of good rpg's, puzzle games and racing games too.
Both saturn and dreamcast, had great games the other didn't have. For example:
Dreamcast had the legendary Soul Calibur, Powerstone etc. Saturn had X-men vs. Street Fighter, Marvel Superheroes vs. Street Fighter and VF2 etc.
Now all Sega needs to do, is make a console, that has the game library of both consoles. Provided that sega, and the 3rd party game dev companies, are willing to make, good sequels to their arcade classics and fighting games, and not the crappy sequels, that we have been seeing for the past 2 decades, on the other game companies consoles etc. But that would be the tough part.
