FFX Sin Spoiler

I bought FFX HD today and I watched the quick look earlier how big of a spoiler is finding out who sin really is?

You find out pretty early in the game who Sin is so I wouldn't say it's a big spoiler.

@nux: Okay thanks

Not that much of a spoiler. Like @nux said it's established fairly early. There are a number of twists that come into play later on that weren't spoiled in the quick look.

You find out less than ten hours in.

It's not really a spoiler at all. You can easily figure out who it is within the first Sin sighting. That happens in the first 15 minutes of the game.
