I didn't check all scenes OFC, but from things I checked everything seems same, did anyone spotted any difference or this ''Revised Storyline'' thing is lie? Only change I see is bugged HUD (probably because of ''changes'') if it's because of changes and I have to start over I will scream...
I think it is best to start all over again. There is a change in the story line for sure. When mc goes to doctor, she says that he needs to "interact" with as many girls as he can in order to get a cure for his condition. So instead of heaving him thinking that this or that girl would be his girlfriend all the time, he is thinking that maybe this or that girl with cure him and make him stop hearing the talking dick (which is also a result of his condition). There is still the story line of the CIA operative which has not changed.
He added a lot of things in the phone as well, and to be entirely honest here, I haven't encountered any of the previous bugs, like the phone for the recording or the translation bug when speaking with Rita.
Give the game a chance, I think it is worth it.
