Linear: The game wants you to complete a task in a specific order.
Non-linear: The game wants you to complete it in your own specific order.

@Pifanjr As I see it most games often have some kind of hybrid between the non-linear and linear ways in how you go about exploring the game. In Assassin's Creed Odyssey (I'm a bit low level, but so far it seems so) you can basically go from island to island, but you are restricted by meeting higher level enemies that will one-shot you if you are not careful. That game basically wants you to follow the main story, but, you can explore to your choosing, even if it will have some limits the further you explore outside the safe zone of your character and enemy level.
No meaningful plot impact, but a big impact on what your character can do and what you're character will face. To steal your example, maybe Frodo and Sam don't face a broken, insane Shelob but one in full possession of her powers. Luckily, Sam has a Holy Avenger sword now, so they've still got a chance. Plot-wise, its still "they have to fight a great challenge" but that battle won't play out the same at all.See, I still think of that as a series of linear experiences. When you drop the thieves guild questline to do some mage missions you come right back to where you left off, the only difference being your level and equipment, neither of which have any meaningful plot impact, so it's still the same experience every other player has.
