There's something missing on Steam, scratch that, there are a couple things missing on Steam and it's not just localized to one place — it's across all regions.
What games are missing? The big Holiday blockbusters — The Crew, Far Cry 4, and Assassin's Creed Unity.
Reddit and NeoGaf have both seen numerous threads pop up stating that certain Ubisoft games are missing from Steam. The missing games were first noticed to be missing in the UK, soon after America, Canada and Brazil noticed the missing games. While the games are no longer listed on Steam, you can still purchase them through Ubisoft's Uplay, GreenManGaming, Amazon or other independent retailers.
The reason as to why these games were removed (or who removed them) hasn't been revealed as of yet, but we have reached out to Ubisoft for comment.
