No, Glamour was already a remake, and always intended to have characters from BB appearing as they were both going to be in the same setting. Then it became a remake with a BB remake being done at the same time as part of it.
I wouldn't say the story was great... It was on par with BB quality wise, with the only real difference being that Kate is a far more likeable protagonist than Max was/is.
Agreed.
If not two separate games, then at least finish Kate's side first, and then do the BB remake. The work that would have been already done (mechanics and points where story/characters cross-over) would have allowed the Max side to be done quicker, especially with being able to reuse the majority of the points where the stories cross that specifically have Max & Kate interacting.
