Some playtesting feedback for Carl Chudyk:
My friend and I have both played hundreds of games on Isotropic, and we both think these free city achievements for splaying and flags are pretty awful.
The cities that instantly jump you three achievements are the most egregious -- I'm looking at you, Dublin!
But the achievements are also just lame, even when you just snag one of them. As others have said, they don't require any set up (like Monument or World or Destiny). They are totally luck-based: you have to draw a city with an arrow (and I've missed out on a splay achievement several times because that color was already splayed in that direction).
I much preferred the first-to-10 castles/crowns/etc. achievements. Those indirectly interacted with the city cards in a few ways:
1) Cities are the most icon-dense cards.
2) Cities allow you to tuck cards from your hand, increasing your icon counts.
3) Cities that splay can increase your icon count.
Also, the first-to-10 achievements encouraged you to do something you wouldn't otherwise do. For example, if my opponent has 2 lightbulbs and I have 7, normally it would be a waste of time to try to get to 10 lightbulbs. But with the first-to-10 achievement, I might take an action or two to do it!
If they keep the splay and flag special achievements (Fame, Repute, Legend, Victory, and Glory), then I would suggest nerfing them to require an action to claim. That way you would have to spend 3 actions to get 3 achievements with Dublin, and they'd still be worth claiming, because, hey, achievements! To reduce the memory issues and to remove the random punishment for drawing a city with an arrow that happens to match the splay you already have in its color, I would simplify the arrow conditions:
Fame: You may claim this achievement if you have a top city with an up arrow icon.
Repute: You may claim this achievement if you have a top city with a right arrow icon.
Legend: You may claim this achievement if you have a top city with a left arrow icon.
Victory: You may claim this achievement if you have a visible black flag.
Glory: You may claim this achievement if you have a white flag that counts as an achievement.
