Microsoft have a bunch of Assassin's Creed games currently on sale. Origins isn't the best price it has been, but I think this is the cheapest the Ezio Trilogy has been so far on Xbox One.
The Xbox 360 titles require Xbox Live Gold, but are backwards compatible with Xbox One. Most of the games have also been cheaper previously (or free with Games with Gold), but there's still some good discounts for anyone wanting to fill in the collection that may have missed out previously.
Xbox 360
Assassin's Creed - $3.98 (Was $9.95) (Gold Required)
Assassin's Creed 3 - $7.47 Was $14.95) (Gold Required)
Assassin's Creed IV: Black Flag - $11.98 (Was $29.95) (Gold Required)
Xbox One
Assassin's Creed: The Ezio Trilogy - $27.98 (Was $69.95)
Assassin's Creed IV: Black Flag - $11.98 (Was $29.95)
Assassin's Creed Rogue: Remastered - $34.97 (Was $49.95)
Assassin's Creed Origins - $59.97 (Was $99.95)
Assassin's Creed Origins is cheaper at cdkeys (plus AC Unity) - $38.39
Assassin's Creed Syndicate is still part of Games with Gold until May 15th.
You're right about Assassin's Creed Origins from Microsoft is not a good deal. In fact it's an awful price.
Assassin's Creed Origins XB1 here for $38.39 with a free Assassin's Creed Unity as part of the sale.
