After scouting the forum and managing not to find what I needed (and not getting the wiki at all -_- ) quick question:
How can I successfully tell my game to have certain scenes if an achievement has been unlocked
AND
how do I prevent a new playthrough from acting as if the achievement has been unlocked?
Or should I instead go with an unrelated variable that will be set to “true” in addition?
I feel ridiculous for asking.
