The irony is that so many PS4 owners thought they needed the Switch to play games
Nope, there is no irony in that. I always buy a PS system first, and later the handheld made from Nintendo. There is no reason not to be a multiple console owner (except if time/money is a real issue) as they are very different systems with different game types.
With that out, I can confirm that my playtime is usually 60% PS4, 30% Switch and 10% PC. So yeah, there is nothing wrong with saying that my Switch is my secondary system, the same way as the 3DS/PSVita were before. Pretty much anyone I know who owns a Switch uses it this way, but being from Eastern Europe many of them play primarily on PC-s.
Does that say anything about the quality of the games? Absolutely not. Could we have a single thread where childish jabs are not the norm? It seems that will remain a dream.
