>>118960my advice is, don't play with him unless you're willing to goof around.
he probably feels guilty for dragging you down if it's a game you're "serious" about, find something fun/silly to play with him during your off time
i suffer from the same problem, except i'm on the opposite side of the fence, i can't find it in me to be "serious" about video games, we usually end up playing the easy ha-ha stuff because having him carry me weighs on my conscience
you have no idea how much i really wish i knew how to play games like i care about the outcome/results…
