One thing is being biased, another thing is recommending people products that don't even exist (officially) based on that bias.
I'm not defending it, but it's all rooted in a bias. Gaming is basically impossible to define beyond 'interactive entertainment'. The scope of what composes
interactive entertainment is so unfathomably large and diverse that it makes for a wide breadth of tastes and preferences.
Unfortunately you have a ton of people unable to break free of their personal preferences and assume the entire medium must live up to their tastes and expectations. They seem a pattern in hardware evolution, game design, and means of interactivity (via peripheral) that they're drawn to more than anything else, and use this as a dumb standard to rate everything. This is their idea of gaming and they can't see it as anything else.
Thus you get stupid shit like "hurr hurr this is a tablet and tablet controls are dumb you dont even need them it should have a traditional controller PS also I like Xbox/PlayStation and it would be better there. 6/10 but wait for the 360 port". It's the same shit we saw with the Wii. It's the same shit we saw with the DS. It's the same shit you hear from some Nintendo fans dribbling obnoxious "graphics don't matter", and equivilent "it's not cinematic like uncharted 2/10 nonsense.
It really just boils down to "This is my favourite platform and my favourite type of game", and that's okay. But then some idiot decided to give these people a platform to rant from, and a bloated sense of authority and ego, and worst of all pay them for it.
