I don't play Jenga. *shrug* Non-linearity isn't imaginary, no...but all it really does is give you (I say you, because it doesn't apply to me) the illusion that something different is happening, when it's not.
Also, I never understood some of the claims of OoT and MM letting you dungeons in different order. Nearly all cases for OoT involves glitching...and if we're going to count that, I may as well claim every Zelda is non-linear because I can hack my way to a different dungeon. MM almost always requires you to do over 50% of the current dungeon before advancing...that's not shifting the order, that's just leaving a dungeon incomplete and making more work for yourself to do.
Anyway, I just don't see the pleasure in it. It feels weird even when I have attempted it. It's like picking up Harry Potter or Narnia and starting with Chapter One, moving to Chapter Seven, going on to Chapter Six, then Chapter Two, Chapter Five, Chapter Three, etc. It feels like the journey and the story was just...sloppy...and ruined.
Something different is happening your doing a dunged with a different set of items, some time more items making it a little easier, or less items makeing it a little bit harder.
