Terror Island writing tip: Specify that characters have names. This makes them more relatable. (That's the title text for that comic.)

I'm imagining something like:

Player: I ask the NPC for his name.

GM: He tells you his name.

There's also online fantasy name generators. Which basically just do that, but you don't need to bother with tables.

Elppin is a valid Troll name.

I like this version better, though I admit it's less relevant to the meme.

What annoys me is when they don't have weapons have distinct special abilities, but they do have different damage dice. You end up with a situation where some weapons are just better than others, and if you think a greataxe fits your character better than a greatsword, you have to choose between dealing less damage, having a weapon that doesn't fit your character, or houseruling that weapons that don't have other differences deal the same damage and ignoring all those stats.

Depends on the magic. Fireball was used in the seventh through fourteenth centuries, so that's not anachronistic. But if you want to do elemental transmutation, that wasn't discovered until 1896. You could have it in steampunk.

And how do you get people to collaborate? People have tried making governments based on the idea of everyone working together for the common good. It never ends well.

Ownership in general isn't some fundamental inalienable right. It's just that if you let people own things, you give them more incentive to make things. I think intellectual property rights are far too extensive, but if we didn't have them at all, how would we pay for R&D? How would we pay for big budget games and movies? Maybe you're happy contributing to openly licensed projects, but a lot of people have to pay for rent and raise a family, and can't take the time to contribute to things like that even if they want to unless they have the money to support themselves.

That's still way more imaginative than anything I can do.

That's what all of it is. They just started naming everything after D&D monsters because they play D&D.

I've heard stories about players finding clues that the DM never intended to leave. Either stuff that wasn't supposed to be important or plot holes. I think it might be good to have a rule that if the players find a certain amount of evidence, then regardless of the intended answer, they're right. Honestly, I think it might be fun to not have an intended solution, and just keep making up details until they find enough plot holes.

I'd think of it as once to set up Chekhov's gun, and once to use it. I think that's a good rule, but it should be clarified in session zero.

Also, if anything depends on the environment, you don't need rules like this and you can directly control it to make sure it doesn't happen often enough to get boring.
