Can you give us some inside opinions on the in-game characters? Who is liked and who hated, who'd stay the same and who'd be changed and how if the game was being made today from scratch?
I think the big difference would have been more complex character situations earlier.
Take Georgina, I’m not sure she would have moved on to the Polyamory arc and stayed in the background with the old work. Instead, she got transformed into something more complex (crush on MC, ex model) toward the end of Chapter 1. In a redo, those elements would have been at the beginning of Chapter 1.
Elena’s father conflicts and self esteem conflicts would have been drafted into chapter 1.
Jennifer, imo, would have also benefitted from a more complex handling in Chapter 1.
I think the characters kind of grew into what they are now, but they would have had that “fleshing out” way earlier. Now that Melody is winding down, there are more insights that would have gone into each characters, and you might have had a larger number of reoccurring but non-sex available characters to flesh out the world environment.
