8. Will there quests that have multiple paths to take, or perhaps even multiple endings? Also, will there be quests that have a non-combat path for people who want to avoid combat?
All the quests in the main quest line have multiple paths. Some of those path choices have dramatic effects on future quests. In one case you have to choose between the supporting the cause of the Golden Saints or the Dark Seducers. Later, you will have to save either the Saints or the Seducers from destruction, but which depends on who you supported the first time.
