As Al stated, plus to explain the differences:
- there was one lewd scene removed from the game, the hot tub. It was already removed in the Ch5 Beta, but the files were still in the folder, just unused. You have to play with a mod to activate them. Or you play 4.5, with none of the 5 content (the whole last day currently in game).
- the other erotic scenes that were removed are mainly partial nudity. The main one being Nami topless when she finds out
Noji was dating., and the other one being Nami waking up next to Nika (which was cute, not really erotic), or Nami with the nipple pump. Nami fans lost out. Bella fans lost nothing, Sasha fans lost nothing (because there is nothing for her yet
)etc.
- All dick renders were removed, as were all renders of Mario with the buttplug. I'm not crying over that. Also, there were no sexy dick moments, they were pure flaccid noodles.
- several animations were cut because the music licenses had to be pulled. Ocean couldn't find music that he felt worked, so he cut them. The animations were 100% innocent story things, not lewd content.
As far as new content:
- the first basketball game is fully re-rendered.
- the heist scene has been redone, and there have been alternative scenes added for some moments.
- Mila's waist and face now mainly stay the same even if her boobs and ass seem to inflate with her mood, scene dependent.
- a new scene showing Sai chatting up Nami, so the punch isn't out of nowhere.
- a new scene with Bella at the college that is bound to end up used as memes.
- there's a lot of little changes that link conversations better - ie things don't happen as much out of nowhere.
So the question is, do you wish to play the version that will continue to the next season, or do you want to relive that hot tub scene?
Simple solution. Download CH4.5 and Season 1. Play season 1, get the themes and story content. Play 4.5 holding control and spot the differences and get your fill of flaccid dicks that constitute 'erotic' content, and hope you don't fast forward through the one lewd scene. Then wait for season 2 getting progessively lewder, and play WiaB in the meantime, as Ocean develops the two games in tandem, and WIaB already has lewd scenes.
