I think for $40 you can get a whole lot of really fun sandbox nonsense out of this game. I mostly really liked it, but found myself disappointed in the parts of the game that we all kind of knew would be disappointing.
You could just pay 15 for Uplay+ for a month and see if you like it.
If I’m thinking about the same deal you are, you can add literally any Ubisoft game to your cart for another 20% off. Slapping on The Settlers II to get the price for the Gold Edition down from $100 dollars to $61 is very tempting.
Edit: And so that would make the normal version $37.
It’s already £39 on the Xbox store!
