In the US? Yeah maybe. Worldwide? Hell no.
In Japan consoles were just keeping business as usual. So there would certainly be tons of consoles being released in Japan, and I imagine at least one of them would have been sold internationally and exported. If Nintendo had decided not to export the NES to the US for some reason, maybe Sega would have and instead we'd have threads about "Did Sega save console gaming with the Master System?".
And like others said, PC gaming kept dominating Europe until like the PS1 came out.
The absolute worst case scenario I can think of is that the 3rd generation of consoles never gets released internationally, and the first console to launch internationlly ends up being the Game Boy in 1990. The Game Boy would undoubtbly take off just like it did irl, and it is certainly a console, so the Game Boy would be considered the saviour of consoles I suppose. With the success of the Game Boy, maybe Nintendo launches the SNES in 1992 or something like that
Edit: Wow the question is even dumber than I thought. Gaming at large was certainly not saved by anyone lol. Even in the absolute worst case scenarios, PC gaming would continue going on.
