Look,
You've to give them cred for doing a proper sp, prior they only had mindless bots running around in SP aka how it was in 1942, bf2. Fact is that scripted events and moments add to the immersion, something you can't capture in the same way with unscripted gameplay.
It will still have its regular open multiplayer , i'd even prefer if the RO2 sp went down this road but obviously with a lot more realistic scripting. I really have a hard time enjoying mindless bot wars in SP, but everyone have a different taste. The mp on the other hand should be open.
Nevertheless my games of the year is definantly RO2, IL2 nothing else even comes close on the PC, finally a good year
