I just played Rust for the first time today, and I must say that I am positively surprised to be able to play for >10hours max in alpha
The only thing which could make it even better for me (and a lot of others) would be lanterns:
Crafted with fuel and metal fragments
Attachable to pillars and walls
(and which use very little, or no fuel at all)
Keeping a (big) house lit with only campfires is rather uneffective and consumes way too much fuel IMO.
I’d be really happy to see this in one of the coming patches
