Summary: The classic JRPG we all wanted when everything after FFX started to fall off from the Final Fantasy games we all loved. Compared to the main series of games, The 4 Heroes of Light would mostly take after FFIII (DS version to be precise), but compared to FFIII, T4HoL is definitely more polished in terms of gameplay. The game also seems similar to the Dragon Quest series (perhaps around DQ3-4).
Summary: I picked this up after playing through miscellaneous 8-bit RPGs on my old Game Boy, plus DS remakes of older Dragon Quest games, and it definitely is reminiscent of those early games. It is not a "real" Final Fantasy game, so in that respect it is like those old Final Fantasy Legend (SaGa) Game Boy games ;) I wasn't sure about the artwork style when I first bought the game, but it won me over after a short while.
Summary: I'd almost say that FF is the wrong moniker for this game, especially comparing it to recent FF games. TBH, it is more like the Dragon Quest games, or the first few FFs. Truly Epic, Truly Awesome. Also, Bravely Default:Flying Fairy (this game's spiritual sequel) is now slated for a western release!
