With The Binding Of Isaac: Rebirth's final, final, for real this time final expansion launching next week, lead Isaac man Edmund McMillen has spoken about his plans for what follows. One answer I'm actually surprised to hear is Isaac 2, a full-on sequel to the roguelikelike dungeon-crawler which has already had a remake and numerous expansions. That won't be for many years, mind. Once Isaac's Repentance expansion is done, one of his main plans is to finish Mewgenics, a weird cat-breeding game first announced way back in 2012.
