Hi Tommy,
here is how I did it. (I'm making an point-and-click-adventure myself with
py-thon & -game, too.)
In my game there are just scenes and actors. Allmost all of the data is in
the actors, even the cutscenes. So I (more or less) only save the actors
with PICKLE.
I'd like to rewrite it someday and try YAML, because a human readable
savegame is much help during development.
