First post is a banger!
In the event you're serious: Performing actions in the game advances time, making you have to plan your actions accordingly. It creates an illusion of a world that exists without you, where people have schedules and things they were doing before you came into their lives and fucked them. If you want to keep playing on your current save file, you can use a
checkpoint mod to travel back in time (possibly breaking your save file in the process), or start a new game and explore other paths and character interactions you didn't bother with the first time.
