I've never understood why something being so old is an excuse to spoil. Many people weren't old enough to be alive when it was last a cultural icon and may not have heard about it until this thread.
I never said being old is an excuse to spoil. My comment was solely in response to OP's comment, which specifically mentioned the fact that this is a thread about Nethack 5.0.0. The fact that we are in a thread about Nethack 5.0.0 is not relevant to the particular spoiler at hand.
