Because you said so?
Like ... these days I'm definitely one of those PCmaster race dude, but I still find it hilarious the language some of you are using. Do you think including these "soul-crushing-monstrosity-words" into your sentence will lend them weight or something? Industry destroying? Like ... yo, I don't know how long you've been gaming, but let me tell you as someone who have been gaming since the mid 90': the industry have been getting stronger every year. And it's not even a linear, but more like exponential growth. If after almost 30 years and there still no sight of the industry being destroyed you mentioned, maybe it's time to re-evaluate your evaluation? Or you just really want to play a false prophet?
Seriously, just be honest and say you just want everything on one platform to save yourself some money, that's all there is to it, that's
the real and only reason. Not because you care about the state of the industry or whatever grandstanding reason you are window-dressing your argument. Like ... it's not even a bad thing so why pretend? It's normal for all of us to have more while paying less, myself included.
