3) A Precursor Orb
Way back in the early 2000s, Naughty Dog released the first entry in the Jak and Daxter series, titled “Jak & Daxter: The Precursor’s Legacy.” Players would assume the command of Jak, a humanoid whatever, and Daxter, a ferret/muse for some people. Players were awarded with Precursor Orbs when they completed side quests, story missions, or just by finding them around the world.
Precursor’s Orbs have made appearances as optional treasures in the first three Uncharted games. Why not throw one in an Uncharted spin-off/sequel? Maybe in the beginning of the game, players have to find a mysterious treasure called “A Precursor’s Orb,” only to face a significant twist that sees players take on a treasure that is not as self-referential. Sprinkle in some good ole’ fashioned Uncharted jokes, about how this Orb seems to familiar, and voila, you probably have an adventure fit for DLC.
