That doesn't have any bearing on the idea of well done Smithing being a fun part of a LOTR game.
Absolutely it does, and the fact that you're not engaging with that shows the problem you're having in understanding the problem here.
This is about themes and styles and tone, and you just don't seem to be seeing those or engaging with those concept at all.
The themes of LOTR aren't affected by the presence of smithing as a mechanic or even something that simply exists. This pretty absurd hyperbole that doesn't stand up to scrutiny.
You said it would be a major gameplay loop.
So you're changing your position completely to try and and claim "hyperbole". You were the one who said it would be important. And it sounds like you're doing exactly what you criticised - making a system for the sake of system, not because it's needed or warranted.
I maintain that in 3rd Age-set LotR game, it would be entirely inappropriate to make smithing any kind of major part of gameplay. It's completely tonally and thematically inappropriate.
And crafting isn't incompatible with active multiplayer, it just hasn't been done in a lot of places. Space Engineers is an example of that in video games, and obviously in the tabletop space most people are still just copy-pasting the same anemic skill check and time gate mechanics, so you won't likely find examples there.
Because you factually cannot implement something like that in tabletop game.
Afaik, none have. We don't have a lot of innovators (re: none) in this space focusing on these ideas, and I don't actually know yet if my own take would count.
That kind of appeal, however, is fallacious. Engage the idea; don't rely on easy excuses to disregard it.
It hasn't been done, and asserting that it should be done for the first time in some entirely inappropriate RPG is bizarre, frankly. The idea that it's a fallacy for me to point out that you're engaging in a fantasy about a system that doesn't, and where you only example couldn't be implemented in tabletop is pretty funny, if nothing else.
Also kind weird to be complaining about the lack of innovators in this space, whilst attempting to complain about a game that's actually innovating, and innovating enough to upset some people. Maybe attitudes like your own are part of why get fewer innovators?
The crux of the issue wasn't what the game does though, just a bit of what is basically marketing. Essentially, "heroic" is superflous when what it refers to is covered by "cinematic".
None of that has any bearing on the game though; nothings lost by the absence of the "heroic" descriptor.
You think this because you completely point-blank refuse to engage with themes or tone. Heroic is very much about tone and style and themes. It's not about the literal minutiae.
As I've said, it seems like you're going wildly out of your way to critique terms that they've defined and are using by their definitions, because you wish they used different definitions. That's beyond pointless mate.
