Soooo ...
A little story of my fortress ... i was tring to play a very hard game by limitating certain parameters. And well, all was going well buuuuuuuuuuut .... one thing is still making the game very easy.
In fact, if you build Temples/Tavern etc... it may appears that a LOT of visitors come to your fortress, even with only 10 dwarves and only few law quality rooms, no artifact etc...
And this visitors frequently want to stays in your dark ugly dungeon for no reasons ...
I don't understand truely why in certain case the number of visitor is reasonable and in other case it's a deluge of visitor... but it seems to be related somehow to the proximity of numerous civilization.
The result is that it is very easy, too easy, to make visitors mercenery elite squad ... I am in my second years and i have my elite squad of full steel armored melee weapon multi-racial guys waaaayyy before having strike down the tiniest quantity of copper ...
I think this could be a huge hole in the gameplay in the future and that this should be nerf one way or another. I guess the best nerf way for that is to rework the "rumor spreading" system that seems to make people come to the fortress by taking into account more of the value of the fortress, of the room that precedent visitors have seen etc ... It should not be logical to have visitors coming to each 200 tick for an ugly little tavern with no music, no performer, no tavern keeper in a fortress with a single meeting hall containing a single well ...
Although, it could be fine too to have cultural preference that make attraction of mercenry from culture we are in war to more difficult than peacefull culture.
To conclude, i imagine that this could be nerf in a lot of other ways, so if anyone have ideas, this topic could serve the purpose of keeping it together :p
(sorry for my bad english :p )
