(...) Poor management culminating in the botched release of the Saturn crippled their first-party efforts beyond repair. While the Wii U was a flop, Nintendo overall has come across as far more competent even at their worst than Sega ever did during the latter half of the 90s.

I don't share the opinion of crippling beyond repair. A new generation marks an opportunity for a reset in image and perception, so the Dreamcast had a legit chance to change Sega's fortunes. Of course this means to come strong out of the gates, but it's here where Sega failed already. The biggest IP Sega ever had, Sonic the Hedgehog, was crammed into a lackluster 3D game. It may have gotten good reviews at the time, but the market reception was that the game sucked. Reviews for re-releases of Sonic Adventure were more in line with the actual quality of the game. The Dreamcast had its chance, but it made a bad first impression that the rest of the first party lineup couldn't offset, so interest in the console waned quickly.

Market reception? It was the Dreamcast's best-selling game. Unless you mean perception of the game, but it must not have been too poor if Sonic Adventure 2 was released, and also sold decently.
