Goatbrush: I can see why you'd think that. But seriously, I just checked out a faces of Max Payne video. Some of the faces are brutal.
F4LL0UT: Don't know if you know but the consensus on Max Payne's facial expression was that he looks constipated. The developers later included a reference to it in Alan Wake and even created
this gif, a link to which would be found in form of a QR code located within the game world of Alan Wake (and yes, it's actually the author of Max Payne who also represented Max in the cutscenes and who Max Payne's 3D model is designed after).
Edit: Okay, I just noticed that you actually included "constipated" in your previous pics' name. I presume you already knew the stuff I mentioned. :P
Edit 2: Oh God, even tinyE mentioned constipation and I didn't notice it. A clear sign that I'm tired and should go to bed (oh yeah, 3 AM - I REALLY should).
Relax, I mention constipation in all my posts.
