Since the release of Deadpool and Wolverine, I've written two separate pieces on the video game adaptation of the "Merc with a Mouth." One was simply "hey, did you know this even existed, it's hard to get now though" and the other focused on the increasingly extortionate prices on the used market.
The issue there was licensing, in that even though Microsoft now owns Activision, the makers of the Deadpool game, the license to the character has long since expired. That means no digital sales, and since the physical copies stopped being made a long time ago, what's out there is literally all we have. Hype from the movie inevitably drove up the price. It's since happened to the X-Men Origins: Wolverine game, too.
