Anno 1800 Gold Edition (55% off Ubisoft Store) $42.75

Discounted 55% from $95.99 to $42.75
I got it for $34.20 with an additional promo code. (YMMV on this 20%, see below)
The other versions are also on sale, but this is the sickest deal in my opinion with all the DLC included.
If you’ve purchased/played games through Ubisoft before, you may have enough Uplay credits (100 required) to get an additional 20% coupon code. To get your personal code, you’ll need to log in to club.ubisoft.com and then go to https://club.ubisoft.com/en-US/shop-discount/ to redeem your Uplay credits for the promo code. Copy and paste in the cart before checkout.
