Quoted from zacaj:
I'm pretty sure line has a fairly old copy, so I need to burn a ROM either way... Interested in the little Gameplay differences, if any...
I didn't have that many plays on the game before I decided to get the home ROMs so can't pinpoint any specific game play or non-swear call outs. I just remember thinking "that seems new" as I played but there was nothing earth shattering.
What I did was read all the threads on this and the consensus seemed to be it was worth it but that was more for the swearing. There were some that said it was not. Here are a couple quotes from a thread:
"also forgot, the sound quality is better with the profanity set, as they are bigger, and the audio is less compressed. It is somewhat noticeable."
"I actually have installed them since my post. Definitely quotes directly from the movie. Sound good and definitely fitting to what happens during the game. I like the violation animation that happens sometimes too. I upgraded from P3 ROMs so there is a large difference for me upgrading to these ROMs so it was very worth it."
I did try and search for any specific game play differences listing but could not find one.
