Direction 1 Side content: Content that does not increase the level limit or present a new story but fit into the existing narrative. The cut content like the upper city and even avernus are good examples of this

Direction 2 expansion content: Stuff that happens after the main story and increases the level limit. For example a civil war within the gith story

Direction 3 more companions: Add more companions starting from act 1. They do not alter the main story nor require content outside of a companion quests and cutscenes
