So I learned this on TV Tropes about Suikoden IV:

One feature (for some reason only available in a New Game+) is the ability to switch your onscreen character to someone besides the hero. If you go into first person mode with a variety of different people, you'll notice that this isn't just cosmetic; the perspective actually changes to match the height of the character. It's a surprising amount of effort for a feature most players will never notice.

Has anyone done this :o Makes me glad I made a NG+ save since I usually don't bother!
