PA's long since fallen into the rut of "see something happen in the games industry, and gabe and tycho come up with some jaded, cynical, or otherwise smartarsed comments about it"
I wouldn't quite agree with that statement. They cover a 360 degree range of events, while most of them just happen to be games, because their core audience is most easily and likely to understand those jokes.
As far as their comedy goes, it's on a much higher level than PvP, 8-bit, VG Cats, Ctrl-Alt, etc. It's not a coincidence they're the most popular. Holkins knows his
**** well and Krahulik evolved into more or less an unparalleled graphic designer from the begining days.
