Can one game win a console war?

Tell that to Nintendo and BotW.
That game alone carried Switch to 10m, so its possible for one game to carry whole generation. Yes it later got more games but if BotW wasnt huge success who knows what would happen to Switch. If people counted Switch as competitor to PS4 and One then i would say that BotW won that war for Nintendo but people dont count Nintendo as competitor to these 2.
Also original Xbox had Halo, that game alone put Xbox on the map. So yes one game can carry console but i dont think one game can win console war.
