To win in any sense you need decent market share. About 10% or perhaps even 20% in some market. Otherwise you lose third-party support and, most importantly, you lose hardware vendors support.
Once you do that it's back to square one where only enthusiasts will play with your platform. And with diversity of components much higher then it was twenty years ago and proportion of enthusiasts much lower than it was twenty years ago your very survival is not guaranteed.
