We need to set out our standards to try to avoid confusion. Because we want to be clear where we are coming from when we express our opinion, so that others will hopefully correctly understand our point of view.
Most posts in this thread are in the third person, not the first person.
I'm also not sure that I buy that
standards is the right word. As opposed to
preferences.
A few years ago I wrote up PCs for a LotR/Middle Earth game, using my fantasy adaption of Marvel Heroic RP. One of them was Gandalf. The player who chose Gandalf asked if, given that we were clearly doing non-canonical stuff, Gandalf could be a woman. I expressed a preference for orthodoxy, and the player accepted that.
If he'd pressed the point, I probably would have relented. It's not that big a deal.
In my current Torchbearer 2e game, one of the PCs has an obsession with explosives, having come from a Forgotten Temple Complex where the religion is explosives-oriented. The same PC, named Golin, has an enemy also called Golin - as the player wrote up Golin's backstory, evil Golin cheated on exams and hence got the apprenticeship position, leading to PC Golin leaving the temple complex to go adventuring.
That's all sillier than what I would come up with if left to my own devices, but does no harm to the game. In early sessions I found the explosives theme very easy to incorporate (the rulebook has rules for alchemical creations), and the Forgotten Temple Complex has been developed by me as this game's version of the (abandoned and forgotten) Temple of Elemental Evil.
Each situation has its own context, its own difference of opinions about what the fiction should be, or should include. I don't think we need
standards to resolve these, or to explain to one another how we have dealt with these differences when we've encountered them.
