Clever 4Ever is the first newer Clever game that I actually prefer over the original. Don't see any exceptional deals on it but I thought I'd mention
Spirit Island on Amazon for $44 is a decent price. Or Horizons of Spirit Island at $14.99 for a less expensive entry point.
Tabletop Merchant has a bunch games on sale including Ark Nova which you might enjoy based on the Terraforming Mars like. The free-shipping threshold is pretty high but lots of good stuff to choose from and even their base prices tend to be decent
Buttonshy has everything 25% off with the coupon code on that page
Some other Amazon deals that are still live: Star Wars: The Deckbuilding Game $15, Cat in the Box $17, Carpe Diem $16, Beyond the Sun $44, Jekyll vs Hyde $12
Oooo lots of recommendations!! Saving this to look at for later think the only know I’ve seen is the Star Wars deckbuilding game. So much stuff to research! Thanks for the thorough response!
