This is the sixth installment of the Fortnightly Topic Challenges Rerun described here and the fortieth installment of the FTCs overall, with topics suggested and voted on here. This fortnight's topic is "Retrograde Analysis" (suggested by Riley) and will span from the 15th of October to the 28th of October. During this period, we will compile the list of relevant questions and post it as an answer to this question.
In the meantime, please go and propose and vote on future challenges!
Everyone have fun, and happy puzzling!

The original suggestion here provides a list of games that may work well with the challenge, but there are many more, and puzzlers are always encouraged to show creativity by finding interesting puzzles outside of expectation.
