I was referring to the original game code.No that would be too much. The recommendation is always to install clean, not to "copy over". This will not even work in all cases because between some updates I would delete some files which would stay if you just copy over, regardless of how often you delete the rpyc files.
In any case, I develop a porn organizer using Pythin and Django named YAPO. Learning Python, I found out that it is always good practice for a program to remove python compiled files when a new version is detected. Mostly, Python can handle it (I mean the full build, not necessarily the Renpy runtime), but not always.
