I just started the game not too long ago, and am enjoying the story that's been set-up so far. Please, no spoilers of any kind here.
 
Anyways, in this game, is it advised to create multiple save files? 
 
I ask this because there is some apparent relationship stuff going on with the characters, and it may be annoying if I were to screw something up unintentionally, and not be able to do anything about it with only one save file (video games <3). At the same time, though, that may take something out of the game if it is fairly dependent on your choices, and reverting old save files may detract from the experience. 
 
Thanks.

It's a good idea to keep multiple save files but it's not really necessary. It's kind of hard to permanently mess up the S-links.

keep one just for backup sake, honestly, unless you're gonna replay 20 hours or more of the game you won't make any real differences on the playthrough.

The only time I ever wished I had multiple files was when I would miss a velvet room quest item that needed to be acquired on a certain date.

I make a new file each save myself!

I have like 10 save slots used :D

Alright, I think I'll end up keeping a few saves at a time, because they're less than 500 KB of space a piece, at least at the point in the game where I am now. 
 
Data corruption is a little scary, so I'll try to keep a new save every once in a while, and clear out the older saves, just in case. 
 
@el_tajij: So far, I am definitely liking the feel of the game. This is my first Shin Megami Tensei game, and I like the characters that have been introduced as of yet. I hope you enjoy your copy!

With all RPGs I keep a backup. I advise you to do the same. I was nearly done with Twilight Princess, and... oh the bug! The game-ending bug!

" @iDarktread:  Yeah same, never played a Persona before, but have been watching the endurance run recently and figure I'd give it a go! By the way, have you chosen to go with male or female? I can't make up my mind which one I'd start with! "

When I had to name my character in the beginning of the game, I pulled this from the Persona wiki: Male Protagonist: Minato Arisato , which is his name in the manga series. For the Female Protagonist, however, there is no "official name", but I found online that some call her Minako Arisato , but there are a few other names as well, if you're interested.

I used the first two slots and alternated when i saved (Slot 1-Slot 2-Slot 1...)
