Not my first but probably my most successful D&D campaign, Planescapin began back in 2013 and ran until July 2016. It finished successfully, albeit slightly rushed due to growing player fatigue. For a Planescape campaign it was surprisingly Prime focused, through my fault rather than intention. The group never really got involved in faction politics or the great conflicts of the setting, with the planes becoming exotic locales for them to visit in between wrestling with plot. What follows is my own retrospective of what happened, what worked and what didn't.
