If you're a diehard FF fan and higher production values and a superior fairy tale are all you need, then by all means, pick Final Fantasy II right up. After all, the reconstructed sequel beats last month's retro remake in just about every aesthetic category. If you're the type of player who puts a higher emphasis on more satisfying gameplay experiences, however, then FF2 definitely isn't the upgrade it appears to be.
One of the least-played Final Fantasies on earth, FF2 feels like its own game rather than a follow-up (which, at the time of its original release, was a semi-innovation). Instead of the traditional experience-building format of the original, Final Fantasy II offers a proficiency system not unlike what's found in The Elder Scrolls; that is, the more you use a skill, the better you are with it. One interesting wrinkle on this idea, though, is the fact that you can actually lose your aptitude with your abilities as well. If you're a warrior who insists on using axes, swords or knives all the time, for example, then your magic-related skills will drop while your physical attributes rise. Interesting, no?
Fascinating as the system may be, it's far too tedious to be enthralling. The only way to increase your health is to take shots over and over again, which forces you to absorb a million unnecessary hits so that you can build a character strong enough to combat later enemies. Moreover, the balance between magic and melee weapons is skewed so heavily towards spellcasters that it won't take long before you realize there's less incentive for powering strike attacks versus magic. In short, the customization feature is artificially robust -- as the best path is rather obvious.
The good news is that while the combat engine is flawed, it's tolerable because of the aforementioned storyline and production value. There's a nice mix of drama and emotion in here and that's a hard feat to pull off with such familiar themes and situations (re: stop the ultimate evil, gather the sacred crystals, etc). My only wish is that the battles were less frequent because Final Fantasy II's encounter rate is so high it's on par with the Shin Megami Tense series. When you couple this regularity of warfare with the game's unusual experience system the feeling of repetition only intensifies.
