When it comes to rushed launches nothing touches the Saturn. They literally rushed the thing to market to get a head-start, so they didn't have the games and angered the store owners who were supposed to sell their systems. Others are botched, but none or so clearly rushed.
They also screwed up by completely leaving the biggest overall retailer in the US (Walmart), the biggest electronics retailer in the US (Best Buy), and the second biggest toy retailer in the US at the time (K-B) out of the loop. They went into full panic mode when Sony announced the $300 price tag on the PlayStation.
The Saturn in general was a complete basket case of a console that had issues well beyond its launch, starting with a complete disconnect between Sega of Japan and Sega of America. They should have listened to Tom Kalinske.
