Did Nintendo save gaming with the NES?

Pc gaming would have been more popular. If NES didn’t happen, genesis/mega drive would have been the one to usher consoles back in.

Sega had created not one, but two relatively unsuccessful consoles during the time of the NES (SG-1000 and Master System). Sega Genesis was created as a response to the success of the NES with a push towards marketing. Had the NES not been a thing Sega probably would have seen the video game market as a niche market and stopped after their second failed system. 

Part of the reason the master system failed (in the US) is because it was crushed by the NES. It sold well in other reagions. Sega was pushing tech to enable its arcade games into the living room and would have continued to do so.
