Wait, then you are you playing it? Unless you are into vomiting, in which case it's all good.

When your game gets interrupted, prompting you into a fat-man temper tantrum which ends up in a toddler getting seriously injured. Then you get arrested.

... Oh wait, that's Xbox.

Alright,

When you join some Gamergate cult and complain about women all day, and spend hours a day attempting to shame them.

Hmm... i guess that's also Xbox.

When you try to explain Mario Kart 8 and 3D World's gameplay and controls to a non-traditional Nintendo gamer and you end up doing so for more than 10 minutes because you try to tell them every technical aspect of the gameplay and how it differed from the last iteration even though they didn't play those games either.

When you buy super mario world for the 10th time because it wasn't on that platform yet.

When you play Infamous Second Son and are surprised that other developers still make platformers or that they're actually good.
