The reason I prefer Penny Arcade over Ctrl+Alt+Del is that I'm not a voracious consumer of games. I have a casual association with games, though not in the sense that would necessarily make me a "casual gamer". These days that means you only play Candy Crush. Anyway, because I do not, as my life goal, aim to play ALL THE GAMES, I don't always recognise a significant new cultural artifact a week after it pops up. Ctrl+Alt+Del does a comic about Rust, but to me it's just two naked guys in the woods discussing the merits of guns over pants. Which is fine, I guess? But when Penny Arcade references Rust, there's a comprehensive news post that goes along with it, incidentally explaining what Rust is and what they think of it. To be fair, Ctrl+Alt+Del does often also put up a blog post with it, though not always, and I'm not in the habit of reading it or looking for it, because it is so often absent.

PS - I'm much more likely to read a book than play a game, in general.
