I stole this most horribly from something TishToshTesh just said on G+. Starting to get the feeling it’s true for me too:
MMOs are designed as monogamous attention whores. I’m just not the target audience for that.
I’d add a link to the discussion and Psychochild’s original post but I, ahem, don’t know how to do that with G+. Yes, I’ve been on it for mumblemumble months. Sue me.
