When I played PlayStation games on my PS2, I would always save several files across two cards because PlayStation memory cards were prone to have files corrupt and, under rare cirumstances, entire cards corrupt. Now that I have a PS3, I still save multiple saves across two virtual cards out of habit and because I don't know if the virtual cards are any more or less stable than physical cards. I've never had a file corrupt, at least not that I know of, but I want to be safe.
That being said, I've been playing Chrono Trigger recently. One thing I noticed is that it has a save count. Every time I save the game, I have six counts added to my save count. One for each of the six blocks to which I save the game. Due to this, my save count is unbelievably high for this early in the game. I've searched for information on why the game has a save count and what it influence it could possibly have on the game but to no avail. I mean, it has to have an influence, or they wouldn't include it, right? Right? So, am I smurfing myself over by saving six times per save? What's the point in the whole thing.
