I don't think that would of went against rules at the quoted post was about a path in the game not a whole new game.
LMAO. The rule doesn't say, "Please avoid discussing or advertising other games
in their entirety in game threads." Discussing any part of another game is, in fact, "discussing . . . other games" and so falls under that rule.
Even if we were to go with your interpretation of the rule, the post I quoted never mentioned a single path only; it very specifically asked about a "wife/mother game" and for a link to be shared.
For the record, I was warning the poster so they wouldn't get in trouble potentially. I'm not a mod and did not report their post myself.
