Greed killed Disney Infinity. Instead of trying to make a fun game, they used it as advertising for their latest films. There were playsets for The Lone Ranger, Inside Out, and Finding Dory

Within three years, they released three different versions of the game, none of which would work with each other. Hell, playsets from the same game wouldn't work with each other. You couldn't drop Jack Sparrow into Monsters University, which was the whole point.
