It happens to all of us sooner or later: despite owning one video game, we buy a second copy of that same game for another platform. What is it about some games that spark us to double-dip on them? On this week's episode of Power Button, Blake Grundman defends his multiple purchases of Shovel Knight while I rationalize not buying Mortal Kombat X at all. It's the first half of a conversation about why we double-dip on some games and not on others and what it takes for a purchase to repeat, but before we can get to that, we need to spend an hour talking about the many versions of Shovel Knight's famous adventure and the latest installment of Earthrealm and Outworld battling it out.
