Never thought about this. I can see where you're getting at, though. I haven't finished P3 yet, but I really like the fact that I'm surprised by new characters joining (of which I knew nothing about before). I even avoided the intro FMVs when I started it, so that I would be pleasently surprised. However, I kinda spoiled my surprise by looking at them half-way through the game (I've looked at them before, but then I could tell voices apart and recognised the voice of the bad guy in the movie and realised it's the new guys that appeard half-way).
Now, I haven't played P4, but I can imagine that I won't be a surprised for seeing some people join the party. Bummer that, but oh well. I really couldn't stop myself from watching a few trailers...
I guess I kinda want to follow the life of the protagonist like it was my own, not knowing anything in advance.
