That part of fallout is cool
Guessing developer intent through pixel hunting is not fun, because the way you actually do in it a video game is to click X on Y, failing in 99% of scenarios because the interaction you thought of wasn't coded in, leading to you paying a heavy cost of 99% clicking on shit doing nothing for a payout of 1% actually working.
This is not at all how environmental interaction works in P&P, despite rusty claiming so. In P&P you can always attempt such an interaction and have it work if it is sensible - because your GM can magically make that interaction be part of the game.
rusty's intense mania with this issue is like the perfect example of valuing principle over actual design outcome.
