A franchise reboot that technically takes place in the same continuity as prior installments.
You have a classic property, one that's made money hand over fist for you for years, perhaps decades, but now, it's getting a little long in the tooth. Maybe it's dated, maybe recent installments have tarnished its name, maybe it's just bogged down in Continuity Lockout. Resetting the thing to bring in new fans sounds like a good idea, but you're afraid the backlash among existing fans to a Continuity Reboot will be epic in its drama. What to do? Well, instead of starting over, dip into the Troper Well and pull out a way of explaining you're not really tossing away the classic stories the fans love. No, this is an Alternate Timeline. Or a sequel set sometime after the events of the old series that mentions the things fans loved but quietly neglects or RetCons the things not so beloved. Or a prequel, or even a separate adventure taking place somewhere else so you have an excuse not to mention the events of the original series. In short, it's an in-continuity remake. A compromise between making a sequel and a remake/reboot.
- The rebooted Star Trek films take place in an alternate timeline, with Old!Spock's presence confirming that everything that happened in the original Star Trek universe still happened, and Word of God that said original timeline still exists, albeit one where Old!Spock disappeared into a black hole.
- Superman Returns acknowledged the events of the Christopher Reeve films Superman and Superman II but ignored the far less liked subsequent sequels.
- The Highlander universe...oy.
- Highlander III: The Sorcerer was a direct sequel to the first film, and ignored the second and the TV series.
- Highlander: Endgame ignored the second and third films, and attempted to merge the first film and the TV series.
- Highlander: The Source was intended to follow on from the TV series, didn't contradict the events of Highlander: Endgame (but doesn't acknowledge them either), and again ignores the second and third films.
- Prometheus ended up being a prequel to the Aliens universe and altering some long-held ideas about the setting.
- An upcoming Predator film is planned to acknowledge the events of the first two films, bringing aspects from Predators regarding clan warfare between rival factions, and ignoring the Alien vs. Predator films.
- Jurassic World recognizes the events of Jurassic Park but glosses over or outright ignores the events of the sequels.
- Highlander: The Series was intended as a prequel to the first film Highlander, but eventually was assumed to be a sort of Alternate Continuity, and ignored Highlander II: The Quickening. Highlander The Raven was set in the same continuity.
- Mass Effect Andromeda is set in a different galaxy from the Milky Way, over 600 years after the original trilogy, with the characters having gone into stasis at about the same time as the events of the second game and in intergalactic space during the events of the third game, allowing the creators the opportunity to not have the climactic events of the Mass Effect Trilogy (and the different endings and player choices) be referenced. This lampshaded at one point when a news broadcast mentions they've sent a message back to the Milky Way but haven't heard a response yet.
Hello, Unknown Troper. You'll need to get known to lend a hand here.
