What's great about heroquest?
What's not so great about heroquest?
think about it, solve it for your group (every gaming group is different...). Then adapt what you like.
For me, great about heroquest is:
* super fast set up
* beautiful game material (look at that furniture.. you just don't find it elsewhere, until today not!)
* simple to learn
* game duration under 1-2 hours, so you need no great game evening planning
* any additional rule is usually found on the game cards, the very moment you need them; and thus it is open to new content
* quest notes allow for any level of deep game (though they are not perfectly used for many of the official quests)
* super fast stow away
not so good is:
* sluggish rule writing
* after some time, there is just not enough game content
* missing overland questing and town modules
So, for me personally, the right way is to clean up a bit the rules; then add more game cards to solve the content problem, do some overland questing ( I was going for sotiris' ideas there).
I did not yet add a town module: I tested some good candidates; but such a thing can easily take more time than the quest itself so I shy away from it.
good in "Das schwarze Auge" was for me:
* content without end (still have some of the books)
* overland and town modules provided
...
all the rest was not good. endless searching for some rule, no game material; a single monster fight takes easily half an hour...
So that's just me of course. If you emphasize some other "goods" and "bads" about the game, your solution will be different. There are many who don't care about game length, so they love to add little frills to the fight system everywhere... just an example.
