For those asking about the activation codes.
Unless Ubisoft changed in the last few months, boxed copies or OEM keys are Uplay only.
The likelihood of this being a Steam key is very low.
Every Ubisoft key sold from anywhere but Steam or Origin has been in my experience Uplay only.
And even the Steam version launches Uplay as does the Origin copy.
Uplay won't die sadly.
As I said before if someone wants to sell me a key.
I'll take it. People are still selling their Nvidia codes which are Uplay only.
I only need one key now.
