It isn't his living space he's from vault 111.
Customising power armor would be cool.
Like you can make a Tesla/Brotherhood armor with the right ingredients.
It'd be cool if you could craft and make unique power armor.
If that power armor is in any way rare. then that power armor hanging up in the garage will go missing as soon as someone turns their back. Especially, when you consider that its owner cannot be bothered to even close the door.
Probably level and "training" related again.... I agree it should be difficult to acquire, and I've a strong suspicion it will be assembled, via 6 separate pieces, which are upgraded via repair/smithing ala Skyrim....
Maybe we need to have that Skyrim system where you can't make Dragon bone armor until you have 100 smithing skill.
This could be usefull in F4 where you can't craft a unique piece of armor unless you have 100 repair.
It needs to be very special, and have enough cons weighed against the pros. Like very high maintenance standards, with taxing skill requirements in things like repair or engineering or whatever. Assuming gamesas hasn't done away with skills to placate the brainless hordes.
Definitely keep power armor training that should be a reward for helping out the BOS and power armor should be rare. I liked how rare it was in New Vegas, you didn't just automatically find it and the ones that you did find were under the BOS faction.
I'm not against crafting Power Armor but it shouldn't be easy either.
Or create a new skill tree under the name of crafting.
My idea is that there should be some power armor components that you can find or you will get a quest from the Institute after completing it they will learn you how to make power armor.
Well I'm certainly not expecting to find some right out the door. That's like mid-late game protection, with a lot of hoops.
Vault Tec with good ideas, that I need to see in order to believe.
Worrying about tiny parts being crafted is rather off, we have no real idea of the technology of the world on certain scales, some factions have built, modified and produced new suits of armor. So machinery/high tech production facilities still exist, or they have learned to develop technology to get around that to produce and repair and make new suits of armor. And if people are making androids and advanced cybernetics like the followers in Vegas, then we really have no grasp of what the old world was capable of, even after 4 games we only have seen a small sliver of the things they have made, both wondrous and deadly.
