My daughter got a second character for Disney Infinity (Venelope and she already has Wreck-it Ralph). Allegedly you can play co-op like this in Disney Infinity. But we have a second controller and hit + and we cannot get it to switch to co-op mode.
Any ideas what we might be doing wrong?
Does anyone have an exact step-by-step of how you do it? (This doesn't exist online after searching for hours.)
