some of you guys must be great fun i MeatSpace.
Vometia more than others. Like your Rudy-impression. Made me laugh.
As a health care face shield provider, I see a lot of point in showing support. But hey. That's me being silly. I know.
Sorry OP. but considering those masks partially contain plastic, a material that wasn't discovered until mid 19th century in meatspace, and the same goes for virology, it doesn't really makes sense seeing them in a fantasy setting that portrays a time era similar to our 13th or 14th century. It's not that I don't understand your wish but I would like to see a game that conforms to the setting already established. Even if that world contains stuff like dragons and shooting fireballs from our fists.
There are games and IP's that don't really take themselves seriously and where the charm is all the goofines and sillyness. D&D Forgotten realms isn't really one of those. Ofc, there have been several easter eggs or dialogue puns referencing the modern world in earlier games but nothing like what you are suggesting.
And whether I'm a fun guy or not at parties. Well. That's not up to me to decide, but I promise you that when I party I don't advocate for semirealism in single player games
