That's not even really the same thing. It wasn't a game with an overarching start/middle/finish split into pieces as much as it was one story that was planned to be successive sequels that kept growing more and more bloated as it went until everyone stopped caring.
A better example might be the "episodic" games that came later like everything Telltale did or Dreamfall Chapters, but those generally wound up costing less as a whole than they would have as a single game anyway (ie, most of the Telltale games were 5 chapters each, each one cost $5, you could generally buy the full season pass in advance for $20, etc), so it's not really the same thing (those are more a case of desperately trying to get new content out while you're still working on it than something that was likely mostly finished and then split into pieces).

Using the console doesn't count.
You can speedrun them without direct cheats.
Life is Strange 2 is pretty expensive for all episodes. Also how can you speed run it without cheating? ---
