So when playing People of the Stars, are you fighting the tyrant several times and the dragon mini himself as the main boss?
This is correct
Or the other option is to play with the dragon as a hunt-able monster in a regular campaign?
This is correct as well
Apparently it's not suggested to play with other expansions if playing People of the Stars. Has anyone added in others like Gorm or Flower Knight?
It isn't recommended due to the fact that some fighting arts, disorders are important to the game, adding fighting arts and disorders from other expansions dilutes the deck a little. Otherwise this expansion works fine with other expansions. I played it with Gorm and Flower Knight and the campaign went smoothly.
