I would love it if the actual courtroom was just slightly more open-ended. I know that’s really hard to do because it could spiral the story out of hand really fast, but it could be contained to individual parts of the case. For example, you could discuss evidence A and follow that thread to it’s conclusion first and then evidence B and follow that through. It’d be nice to do things in different orders when possible. I get irritated when I see a clear contradiction, but I can’t follow the thread until I present another piece of evidence first. This could potentially solve that.
While it does skirt some game mechanics, probably due to it being a movie and it’s a strange medium to adapt, it also does some really cool subtle things with the mechanics. For example, in the final major fight all of the characters attack in the same order. They’re in initiative!
