1. The era will simply involve you collecting every animatronic. Each animatronic will have a quest for you to complete in order to have them join your party. It can be fetch quest, a quest where you go kill x thing, ect. Then once you get all the animatronics you do a fight and then the era is over. (will have CC style parties where you can mix and match characters)

2. Similar to how FAE did 1987 originally, you will be able to pick a group of animatronics to join you. There will be a dungeon for each group that you need to beat. These dungeons will be themed around each group. After beating each dungeon there will be a final fight and the era is over. (Your party will be locked to each group of characters except for the end of the era with the final fight)
