Well, The only thing I didn't like of all this was IT WASN'T REAL!!!
I think the game would be better if things like this could happen from time to time! Monsters than only in singular combat could be destroyed, Monsters invasions, Dragons, tales of relics to be found, etc
A bit more RP!!! 
BM is great also because it's mostly player Vs player but there is some room for players Vs gamemasters (lots in BT, less in Dwi). It'd be bad imho if all islands turn to be players Vs gamemasters.
I heard lot of people who wants Netherworld attacking everywhere maybe because things in their realm are boring right now but low fun it's players' fault, it cannot been solved by gamemaster
