I have read somewhere that they will take down only online modes and DLCs on some of them, I don't know what's accurate. But anyway as someone who have bought almost any AC and Far Cry game from Steam, I'm very disappointed and if I knew it will happen perhaps I'd reconsider buying them.

If I bought a game I thought I'm supposed to own it forever, like having a physical disc but digital. It's yours. That's the point of "owning" it, I didn't pay to rent it. I get it that sometimes online modes can be shut down and I'm ok with that. But not having access to SP or even a DLC that I have paid for? That doesn't make any sense to me.

And if such thing happens today when they can take an access to something YOU PAID FOR without asking you, who knows what can happen tomorrow.
