So i am a big fan of having a daily expedition in the game, as a way to give another option to just playing what is on your cycle.
That said, im surprised they are not utilized better as a way to spice things up. Daily expeditions are currently not very different than normal maps, or atleast they don't feel very different.
I would suggest, that Daily Expeditions are really odd! Like a place, where experimentation can be done and special situations are put forward. Like what if you only had 1 race of villagers to play with? That would make a very different game than the normal games.
Such unique changes would make me play the daily expedition as many days as i could and would add longevity to the game. Take the chance and if its a bad setup, there is luckily a new one tomorrow.
