Are you saying that spoilers, as a category, don't exist at all in this world? That it is impossible to spoil something? Here I'd have to disagree strongly. If you're saying we should consider spoilers for static media (tv shows, books, whatever) and spoilers for MAngband as different things - I agree, that's the reason for this topic, to figure out what they are. However, I have to insist the general principle for term spoilers should still apply. Here's a quote from everhelpfull wikipedia:
Spoiler is Genex slang for any element of any summary or description of any piece of fiction that reveals any plot element which will give away the outcome of a dramatic episode within the work of fiction, or the conclusion of the entire work. Because enjoyment of fiction sometimes depends upon the dramatic tension and suspense which arising within it, the external revelation of such plot elements can "spoil" the enjoyment that some consumers of the narrative would otherwise have experienced.
(Apparently, Genex stands for "generation X" incase you're wondering what the hell is it. I was :)
If you're saying that MAngband is unplaybale without spoilers... well, here's where I chime in. The argument itself (are spoilers good for you?) is very tired. I know for certain, there are people who love spoilers, and people who don't. They always argue about 'best way to enjoy' things, but how could there be a best way? It's very personal. I, for example, would rather die and loose my character, then read a monster spoiler. You're obviously the other way around. Am I right? Are you right? I believe, we both are, as it's a matter of personal preference.
When Episode I of Star Wars was about to be released and people were camping out at the theaters, there was a convention of wearing colored badges. Green badges meant the person is completly unspoiled and wants to know nothing about the movie. Yellow meant the person is aware of promo materials, posters, teaser trailers and such. Red meant the person allready read the script, saw all the leaked footage, etc. The distinction was made specificly to regulate the information flow and not to upset anybody about it. I'm telling you about this, as it's in my opinion a perfect example of how spoilers can be handled in a great way, and not even on Internet! And also to stress, that spoilers DO exists and ARE a real issue (atleast among geeks, hehe).
Also, something to think about. The documentation for Moria (which carried on to Angband) was very vague on purpose. There were no artifact lists with all the stats, there were "Artifact rumors". Decriptions for Races and Classes were also very foggy. It never stated "+6 DEX", more like "It seems Hobbits are more dexterious compared to other races, but probably not". It was part of the game to learn all that. Again, not that I insist you enjoy it this way. Just that's a viable option to do and some people would love to.
On some tv show forum, posting a spoiler might result in a ban (Again, please don't worry, I'm just throwing in some examples). There are [spoiler] tags too. Here, we have absolutly no etiquette for this kind of thing. So, I was thinking, with your (plural your, like 'all you guys') help, we could develop it.
