If you went back in time to 1999 or 2001 and asked the then-young Valve community what was their favorite thing about Valve, odds are the word “comic” might not have come up much. But now, in the year 2011, that word might get quite a few mentions. With the help of the great Mike Oeming, Valve has made six TF2 mini-comics, one L4D comic, and one Portal comic, all of them absolutely brilliant. But they’ve always been web-exclusive. So when’s Valve finally going to do something about that?
