Worlds of What If: A Series of Video Game Alternate Histories

[Salnax]

I'm working on an epic history. The big one: What if the PlayStation was never created?

So far, I've come to a few conclusions, but I'm being held back by my limited knowledge of all things Sega. Does anybody have a concrete reason why the Saturn lacked a real Sonic game? How much did the Saturn cost at what points in time? And what Saturn games should I know more about? Thanks!
