Well well, this is something you guys here seens to be more reasonable about than in other discussions i saw about. Mostly Skyrim is the subject, but as Zoro said, i think that *my* standards for lore-friendly mods apply to all the games.

I dislike most outfits from Mass Effect, for example, for them being something too much futuristic (that space looking), and the same for guns. See, this is not about the ammunition used, but how 'curvy' and refined the weapon or outfit is. In fallout we have ultimate technology, but people seem to like making them in an old fashioned way, and i like to remain this way :p
Mods that add shaun launchers and that sort of thing, and even most XXI weapons i just pass too. My weapons mods are Mauser, grenade launcher, Remington and Crossbow, only. For clothes... well, i installed lots of different armors and skimpy clothes, and i don't really care much about because i only use them for SS, or in specific moments. Running around with Bunny Ears is a bit weird for me, even me being a person who likes this kind of thing

I think that a lot of things can be lore-friendly. The point is exactly this, FRIENDLY. We are not talking about something that actually exists in the game lore, but something that COULD exist without breaking it

This apply for TES games, in my opinion. Running around Skyrim using some kind of skimpy ARMOR (not bikini) is as lore friendly as any bandit using fur armor. Oh, let's just avoid talking about Macho and Thomas dragons...

There is a mod that changes the payload for the nuke launcher to look like baby shaun

Oh yeah, now that you mention it, I remember that.
A Shaun the Sheep launcher would be great, though.

For me a lore-friendly mod is a mod that can logically be explained within the game. For example a mod that adds a m-16 or one of the modern variants to fallout could be lore friendly since the service rifle existed in fallout NV. Some of the skimpy clothing mods for fallout could be lore friendly since adult clothing does exist in fallout lore.

Fallout for me is kind of flexible when in comes to lore-friendliness of mods cause the game is like a mix of old and new. As long as the mod is not too high tech and not too cartooney at the same time, it's still lore friendly to me. I usually tend to download mods that makes sense in the Fallout world but I'm not very strict of it

Lore Friendly to me is along the lines of fitting well into the game as a whole. Like Fallout you can be lenient with as Broccolimonster said, but games like Skyrim are a bit more of a gray area. Like Fallout you can put cars, super hero costumes, mega lasers from space, aliens, and a whole lot of other stuff. As long as it fits into the game, then your okay. (For instance, mods like pokemon mods AND Magic are not lore friendly hehe)It has to fit into the overall theme of the game, which is pretty easy to do in some cases, as its lore is somewhat whacky.
Skyrim on the other hand has to stick to its fantasy motif, and therefore is constrained to certain elements.(You have magic in this world, dont try to be driving a pickup truck when you can easily fly). Anything that introduces lasers, or terminators, or anything futuristic is off the table. Creatures also have to be considered. Creating your own is awesome sure, but is it lore friendly? Probably not. Its all relative to lore. Like you cant bring Martin from oblivion back from the dead just because you liked him. That defies all that is Sean Bean! Let the man die!

But see, in the end modding is about fun! Not about being Lore friendly. Lore friendly is great sure, but so is a rocket launcher that shoots babys. I am all for lore friendly mods, but if it comes to choosing between a lore friendly mod and a mod that lets me become Doctor Who, Im picking the tardis.

...I mean "BRAINZ!"

But what about the dwemer? What if they made a magic terminator?

As the saying goes, "A wizard dwemer did it".

Mods that I think fit into the world such as armor ports from the Metro games.

I dislike and don't consider "slooty" armor mods lore friendly.

Same, I refuse to take the mods that are not lore friendly, I refuse to take the mods that are not lore friendly, I really need to stay in a post apocalyptic world. Many mods repulses me, because they destroy the background and form an incoherence.
Most survival games as Metro are for me lore-firendly, but this is very subjective
