Ok I'll teach you one thing or two, because clearly you are talking without having the starts of an idea about the subject.
As said, they are testing versions. This mean that:
- They have bugs, typos and all ;
- They don't even include nothing before and after the part they cover ;
- It wouldn't be surprising that they don't even include the totality of what they cover ;
- They are tries and don't necessarily match what will be in the release.
If the game was a car, having one of those files would be the same than having the prototype for the backseat. A prototype in plastic, wood, or whatever, that have no other purpose than having something full size to see if it looks as good as it seem on the paper.
Accordingly to the names, among the test version there's :
- The VR scene from the chapter one. It's what Notty used for the test of the new VR UI, so it's in an early stage state (she was still not totally sure last time she talked about it) and it include bugs ;
- The CoC scene from the chapter 5. Here again it's an early stage, testers also do the difficulty balancing ;
- What is explicitly named to be a demo, there's pre-early stage content ;
- One scene with Sarah.
So, still if the game was a car, you would have a wheel, the backseat, the back left door and one piece of the motor.
Wow, great, wonderful...
Of course, there's also the chapter 5 (because yes it is in the list). But knowing how Notty works, there's 80% chance that it's only the chapter 5.
And when I say "only", I don't mean that the chapters 1 to 4 are missing. What I mean is that it only content the "introduction part" of the chapter, and potentially a part (but just a part) of the free roaming. Therefore, it's at most a third of what will be released as content for the chapter 5. And of course here again in an early stage, therefore not even what you'll effectively see when the game will be released.
A test isn't just an "hey, is there bugs in my game" thing. It also regard the pacing, the balancing, the scene orders, the feeling carried by the dialog and the CGs, and so on.
I'm Not Thea Lundgren! will correct me if needed, but I wouldn't be surprised if between the first "chapter X" test version and what finally end in the game, there's around 50% changes.
Someone named George. R. R. Martin, well, to keep the comparison, what you want is few pages that aren't even following, randomly took from his working notes. What is the interest ?
