Although I have not been that fond of AC3, I started the Uplay app today and was informed that I can download it for free - it is evidently their 30th anniversary. They are evidently releasing 7 PC games for free, one each month.
Can't beat the price.
I've been looking to get FC4 for a bargain price, and I would like to get get the AC game set in the middle east (can't recall the name at the moment).
