A good old-fashioned dungeon crawl
Difficulty should be on 'Normal' or higher.
Only the digging of dirt/grass and any ores are allowed. (Except in Emergency, of course)
********* simple, no? **********
This map was designed for groups; going in alone would not only take a stupid long time, but would also be nearly impossible.
It would take literally months to see everything.
Even with a group I can guarantee that all the extant places to visit will not be experienced.
Go anywhere you want! This is a relatively sandbox map, and just because we tell you to stay away or go somewhere doesn't mean you have to!
On that note, remember to keep your eyes open for what might be called easter eggs! Just keep in mind that finding and exploring the obvious easter eggs may be more deadly then anything in the castle proper.
Personally, I will feel saddened and ashamed if I don't kill more than half of any party . . .
Suggestion: Scoring could be kept by assorted loot, just list all ores (smelted or not, doesn't matter) when you quit the map.
