I don't think FFX's story had to be told from Tidus's perspective. I don't think it had to be told from anyone's perspective. Maybe tell the story from the player's perspective. It's just a narrative. FFVII wasn't told from Cloud's perspective. It wasn't told from anyone's perspective. It was given to the players as needed. And X could have done the same thing. Their mistake was trying to force us to feel like we could relate or care about that whiny asshole so that's the eyes they gave us. I suppose he is probably highly rated by Square and/or Japan? Ugh
