Exactly what the thread says on the box. What all exactly is saved on a route when you save the progress of your session in Driver (i.e. not the actual Session itself Surveyor) and is there a way to extend that capability to things like scripts and third-party content. Like, for example, if someone were able to somehow implement a 'campaign mode' route which would obviously necessitate the ability to keep track of data over multiple instances of a session as one plays through it, but this could also extend to less complex areas like preserving soup tables in a script across multiple playthroughs of the same session, or maintaining consistent weather between saves - as in ' Hey, why is it sunny now? Last time I saved it was black as pitch and pouring rain?!')
