Have a question about how the TVTropes wiki works? No one knows this community better than the people in it, so ask away! Ask the Tropers is the page you come to when you have a question burning in your brain and the support pages didn't help.
It's not for everything, though. For a list of all the resources for your questions, click here. You can also go to this Directory thread

Come for the Game, Stay for the Mods is a YMMV item about the original work, so yes, it should be listed on the YMMV page for the original work.
They also deleted it from YMMV.Starbound and deleted Crosses the Line Twice from YMMV.Palworld, neither with edit reason. Since this was their first notifier for deleting YMMV, we're going to just keep an eye on them for now.
Suddenly I'm... still rotating Fallen London in my mind even though I've stopped actively playing it.

DialgaX removed
the entry for Come for the Game, Stay for the Mods on YMMV.Stardew Valley without an edit reason. I've sent them a notifier for removal of YMMV.
As far as I know, the trope is YMMV and mods, being akin to fan fiction, can be referenced in the YMMV page of a work.
Should this be restored?
