On an individual to individual basis, absolutely nothing.
I'm an xbox fanboy because Xbox was my first console, and I only have time/ money to primarily buy games on one system, end of story.
However, unfortunately, fanboy culture has overtaken the media / journalism industry. Just take a lot at how ridiculously inflated reviews for Apple devices are compared to MicrosoftS, HTC, Nexus etc.
Its even worse on the movie and videogames front. Just look at how many blind 10/10 scores MSG5 got. Fueled with nothing but fanboyism.
The fanboy culture and overhype culture is whats really putting me off popculture at the moment.
I have zero interest was watch movies when they release in the cinema and rather wait for hype to die down and form my own opinion, you know cause fanboy opinions/propaganda is contagious as fuck.... and that brings me on to the next issue... social media... but thats for another thread I guess.
Yeah the entire gaming media are cult followers of the Kojiminati lol what a coincedence
