I've played Final Fantasy: The 4 Heroes of Light for a few hours now (I have no idea how many hours exactly, as the game doesn't seem to keep track of such things), and thus far I've thoroughly enjoyed the experience.
I haven't even been bothered by two of the issues that other owners of this Matrix Software-developed game have complained about on line--one of which involves auto-aiming during battles (basically, you can't choose who your characters target with weapons, spells or items) and one of which involves item management (each of the game's eponymous heroes is limited to carrying 15 items--including spells--at any given time).
So, where does the "but" mentioned in the headline come into play? Well, it comes into play while dealing with the game's propensity to pull characters--and all of their weapons and armor--from your party without warning.
This first happened to me after defeating a boss. Once the battle was over, a key member of my party walked away without so much as an "adios"--and took a lot of my hard-earned loot with him.
Thankfully I had saved just before I confronted said baddie, so I restarted the game, stripped that party member of all noteworthy armor, weapons and spells and fought the boss again. In the end, it wasn't a big deal--but it was rather annoying. (The moral of this story: Save as often as possible while playing The 4 Heroes of Light.)
Don't let that (admittedly annoying) detail keep you from giving this game a go, though, as I think it'll be well worth your while if you're any kind of Final Fantasy fan.
