I don't. Computer games take a huge amount of intellectual effort to make, does printer ink? (maybe at some point yes, but certainly not now!)

Edit: Though maybe you're talking flappy bird and I'm talking triple-A, actually impressive boundary pushing game. We may just be talking past one another

I am not playing 3D games developed by team by hundred of people on the color of my printer paper. Thats why.

And if you complain buy a laser printer and never complain again.
