I have no definite answer. It's necessary to know the specific source or genre to determine if 'Phantom Liberty' comes after the main story. Could you clarify?
Well, the start of Phantom Liberty could be indicated by certain events, characters' actions, or maybe a specific chapter or scene. But it really varies based on the details of the story itself.
In most cases, you should be able to do Phantom Liberty after the story. However, it's possible that you need to meet specific requirements like having achieved a certain level or completed particular side quests.
The main story first. You'll understand the basic world and gameplay mechanics better. It sets the foundation for everything in the game. Then, when you move on to 'phantom liberty', you can fully appreciate the new elements as an addition to what you already know.
