ok...
The boardgame was in french and I doubt it was ever translated in any other langage.
Every post I can do here is based on my experience of the boardgame, which is a really really good game.
My previous post was quite unclear for people who don't knoçw the boardgame, I admit...Sorry.
In the boardgame, conquistador leaders were able to disrupt the social structure of natives by their only presence. This simulated the behavior of people like Cortes in America.
So, the conquistadores, with a tiny troop, are able to 'defeat' entire provinces. But, as the same troop and conquistadores were obliged to advance into unknown territory, players had to roll on a table to see the fate of the troops, that can simulate disease, accidents etc etc...
So your troop + conquistador could, maybe, completely disappear into the amazonian forest.
My (too short) question was : someone know if that kind of system exist in EU ?
Sorry again for the previous post
