i personally don't see the point in playing it like in that youtube vid, takes the whole fun outta the game, and ur right, not having to fight the final tyrant is boring, although i think that only happens if you get the really bad ending..i may be wrong...on remake ive got the 2 best endings so i have always had to fight the final tyrant..however on ps1 i did a speed run, which i had to get the bad ending to complete it quick so didnt have to fight tyrant.
