Nope. They lead to fighting new unique enemies and more ancestor swords for noctis. Also need to dungeon areas you otherwise would miss. Also lead you to parts of the world youd miss
If you seen one enemy you seen um all
If you seen one dungeon you seen um all
If you got one more unique item you got um all.
If you seen one part of the map you seen it all
Not true.
Just stop bruh. You played casually and are whining about your casual experience. You barely did side quests which are fun and lead to unique experiences. You threw potions at combat because you didn't want to take the time to learn how to finesse this epic gameplay. You rushed it. I'm sorry
