They won't listen to reason. I tell them my old machine is better graphically than the PS4 and we could share a huge library of games on Steam with family sharing but all they care about is Skylanders. I thought they were raised better than this, I can't even look at them.
They probably know what's more fun than you do since gaming on pc isn't really all that great or all that fun, take your fanboy glasses off and open your eyes for once and stop forcing them on what you like instead.
I'm not at all against console gaming. Love my Wii U and used to have 360. However, saying PC gaming isn't fun is just silly. I just had the most fun in a while playing Day Z with friends.
