So, Nintendo Is The Only Gaming Company that Can Survive With No Third Party Support? If Not Who Else? (If each Company Had Their Own HW i mean)

Sony does have plenty of 1st parties, and could go into different genres if they needed to.

Microsoft can't, because they only have like 3 or 4 relevant IP... maybe 5, or 6 if you wanna include rare, and Battletoads, and Killer Instinct.

Nintendo... Obviously can. Smash brothers, Mario, Pokemon and Zelda games are powerful. I've never owned a nintendo console in my life, and I recognize that.
