"It Takes Two" is a co-op romantic comedy in which two people are transformed into dolls by a magic book to solve their marital problems. While it can't be called a guaranteed seller, it still seems to be a hit, with Hazelight Studios, the developer of "It Takes Two," tweeting that the game "has sold over 1 million copies and is still going strong! Thank you so much for loving our game.

Studio director Josef Fares said, "This shows that there are definitely players out there who want to play our co-op only games as well! Thank you all. We hope to see more games like this," he added. [In her review of It Takes Two, Rachel Watts summed it up as follows. "It's refreshing to play a cooperative game that doesn't feel arcade-y, and [It Takes Two] is one of the best story-driven multiplayer games on PC, right up there with The Dark Pictures Anthology and the two-player campaign in Portal, which is pretty Cozy. One of my favorite co-op experiences is the quiet, introspective "Journey," but if "Journey" is a co-op adventure where you don't say a word, "It Takes Two" is a co-op where you never stop talking."

If "It Takes Two" is not to your taste, don't worry. Joseph Fales has promised to offer $1,000 to anyone who gets tired of it.
