Focusing on a topic that isn’t as laugh out loud funny as those in recent Sunny episodes, the show tackles online gaming, and how easy it is to succumb to the virtual world. That’s not to say “Charlie Rules the World” doesn’t have its moments, because it does. While Mac (Rob McElhenney), Frank (Danny DeVito), Dee (Kaitlin Olson), and Charlie (Charlie Day) are immersed in the game, “Techpocalypse,” Dennis tries to keep a foothold in real life.
