So Assassin's Creed Unity, we've already beat that horse to death long ago, but here is something about it once again.
Look at the amazon page right here

If you are reading this at the present date, you'll notice it is not 10, not 20, but 30 DOLLARS OFF ORIGIONAL PRICE. Wow. That is a good deal, but it is also one of the worst things a game company can do that in the long run kills the industry partially. Why buy a game at launch when it is just going to have a cray ass sale like this? There seems to be no point in pre ordering a game either. Half off is a lot, especially for only being out for about a month. That is a joke. I get that Ubisoft wants it to sell like hotcakes, and it is, Xbox One Version and PS4 version are currently at #1 and #2 spot on amazon video game orders. However, it also at the same time burns a lot of money from then, becuse honestly, fans were probably gonna get the game eventually anyway no matter if it is on sale or not at all.
Other games have done this too, Just Dance 2015 (Recently Released and also by Ubisoft) Is only 20 bucks on select consoles... that is only 40 percent of what it was at launch. Recently also their was a sale for Titanfall from 60 dollars to 20 dollars.... that is some serious sales, but it ruins the fun of getting a game at launch, it really does.
I almost never pre order games anymore, unless it is a huge game for me like Smash Bros, that was the only game I got at launch all year, and even then I was reluctant on the situation.
