Great to hear your thoughts on Unfair! :)
The play time taken tends to be longer on the first play, because people are new to the cards, reading the card rules and flavour text, looking at the illustrations, etc. That gets faster as players become more familiar with it - we have a playthrough online showing a 4 player game can take only 80 minutes without rushing, including setup and packup, https://boardgamegeek.com/video/109348/unfair/4-player-playthrough-game-designer-joel-finch
I also wanted to note that when an attraction is closed, the bottom card is turned over to mark the attraction as closed, but all the stars including its upgrades aren't counted - the whole ride is inoperative.
Thanks for mentioning that the City events (and the events in general) can be defended, and that you can learn to build your park to prevent or reduce the damage from them - that isn't something that all reviewers are picking up on.
Glad you liked the theming of the cards - the pirate super attraction you mentioned is one of my favourites because it lets you bury treasure :)
