If you "tolerate" Trump's active destruction of the nation then you're just a traitor, no matter how you vote.
It's like people are saying "mayonnaise is great because you can add it to any meal", which is technically true, but meanwhile salt is right there being ignored on the shelf.
I think you're misinterpreting this discussion.
This is not something unique to dnd! In fact, DND is not even especially good at this!
Of course creativity and flexibility are not exclusive to D&D. This discussion is not about D&D vs. other RPG systems, it's about the explicit permissiveness of D&D. Basically, some people consider the rules to be permissive (e.g. everything not explicitly forbidden is allowed) whereas others consider the rules to be restrictive (everything not explicitly allowed is forbidden).
My point is that the permissive interpretation is better for gameplay, and I think that argument would apply to any gaming system in general.
Assuming this is a desktop PC, prevention is much better. Get a case with dust filters (preferably removable) on the intake fans or just add some to your existing case. I would call this essential if you have pets.
All of the actors for Command & Conquer: Red Alert 2 were fantastic, but certain things stick with you forever.
Oh yeah, a lot would depend on metalworking sophistication. A fantasy world might be able to produce steel for swords, but precision mechanical parts? probably not. Modern automatic guns, even semi-auto, are probably not possible.
But your basic grenades, fire lances or hand cannons, and cast bronze or iron cannons should all be well within the capabilities of your average Dwarven settlement (you guys can't cast a 10-foot long bronze tube? how are you even dwarves?)
I can see lots of applications for these in a world of magic, first and foremost delivering various magic-enhanced projectiles (cannonball of frost, bullets of psychic damage, etc).
Also, do any specific metals have special properties in your magic system? Could a mythril bullet simply pass straight through a magic shield as if it wasn't there?
Does iron inhibit a mage's casting abilities? (hit him with iron birdshot - no need for accuracy - it won't hurt him much but some chunks of iron embedded in his skin might fuck up his attacks)
Are silver weapons particularly effective against werewolves, vampires, etc? Fuck it, silver grenade, problem solved. Or maybe make some holy-water-tipped bullets like Hellboy, or melt some holy relics down into bullets.
Magic abilities take years of training to use effectively in combat, and maybe people with innate abilities. But given enough supplies, you could train a hundred peasants to operate hand cannons in a month.
Any half-decent alchemist would definitely stumble on a few explosive mixtures just through normal practice.
If I can't see them, they can't see me!
Nobel Peace Prize material right there, folks.
A free action that grants a skill check to get +2 to hit on your next attack as a reward for missing is wildly disproportionate. There are feats worse than that. If this is a thing people can do why would literally everyone playing not be constantly chewing up the floor in every encounter?
Ok, yes I can see the potential problems but I think they're easy to handle by just carrying out the action to its logical outcome - which is that the player just ate a handful of gravel. Now if they're a dwarf maybe that's not an issue, but also a dwarf eating gravel might not be any more intimidating than a human eating popcorn. On the other hand if they're an elf or a human or something, well even if they pass a constitution save to not immediately start puking, they're getting broken teeth, a mouthful of rock dust, and future digestion problems.
Sure, they can take an action that is technically possible within the game world, but actions have consequences. The gravel didn't just disappear because they succeeded on the intimidation roll.
Broadly speaking objects that are worn or held are exempted from automatic manipulation by spells and effects, though this is usually called out in the description of the effect.
I agree this one's more of a stretch, I'd say specifically because Mage Hand Legerdemain has specific rules about worn/carried objects that can be manipulated, which implies that anything not defined there cannot be manipulated.
Only problem is that cost of living problems are world wide and not just NYC.
Literally: "the problem [with the proposed action] is that it only applies to a specific area and not the whole world"
I didn't twist anything. Your comment doesn't contain any more nuance than that.

He should've been imprisoned when he refused to return all the classified documents they found at Mar-a-Lago. That should've been the end of it right then and there. There are people in cells at Leavenworth for much lesser security violations.
