Hmm, are you serious? If you played the original version without mods, you should have realized right away that there are a lot of differences now. Both differences and completely new events.
Yes, there is even something taken from the Glamour (the developer denies this), such as access to cameras.
But what is more important is the appearance of Alice's clothes.
For example, in the original, she was wearing jeans before Kira arrived. It's funny that Max could have asked her to take off her pants during a foot massage at the TV, but due to the insufficient level of various skills, Alice was not ready to go for it. In the future, she always wore only a T-shirt. Just like in Glamour. Even after a shower.
In Alexey's version, she got clothes and didn't stop wearing jeans.
So, the original BB is a great concept, not implemented properly in 13 months of development. Interestingly, towards the end, Alice's excitement is related to the experimental college. We found out about this a few years later in Glamour.
Glamour is a visually and technically more advanced game, somewhat forced at the beginning, and focusing more on the goals of the leadership of the experimental college.
BBAS is a great interpretation of the original and partly Glamour, including many of them, but more expanded with the addition of something new. Plus, it's augmented with animations.
