You're assuming the player is inexperienced with playing RPGs in general though, this isn't 97 anymore and the JRPG genre has been mainstream for well over a decade so I don't think it's highly unlikely that levels will be an issue since most players tend to grind levels out of habit nowadays. Second, you're also assuming they are not using a guide of some kind at all in an era where Gamefaqs is every gamers close companion and is as simple as turning on your phone to look up. I'm even just going to assume they simply have a list of Enemy Skills spells, and nothing more, not even how to get them just the name of the spell and the critter that uses it, but like I said, most of these creatures will use the spell in the first two rounds if you don't go all gung-ho on it, and just nuke it with a summon or just mash the X button. I did say it required a little luck but seriously, a few attempts to obtain a Disc 1 Nuke is not much of a hassle for total dominance. Though the easy way to win, is to just poison him with Bio and just spam potions and cure to outlast him.

My whole point was simply to show that VII has it's fair share of break-ability and is not somehow "magically" not as breakable than other games in the series in this regard. I don't even consider the break-ability to be a mark against it, though the end game is pretty sad but it's not like a majority of the series isn't in the same boat with that problem. Though I still argue Lv. 3/4 Limit Breaks are pretty unbalanced and account to as "I win" buttons that can easily be exploited by even a rank novice. Just learning how to obtain them is enough to allow even the most inept player to just grind for a bit and reach Disc 1 godhood. Honestly, FFIV is probably the only game in the series that is remotely balanced in terms of not giving the player an overwhelming advantage.
