Released: 1997, PlayStation
SaGa Frontier is the seventh game in Square's long-running SaGa series. It's an open-ended RPG with seven separate scenarios, and unfortunately, a sharp learning curve and some seriously uneven difficulty, which caused many people to quit playing before really getting into it. Being one of the first traditional RPGs after the release of the wildly-successful Final Fantasy VII probably didn't help its poor early reputation.
Deadlines absolutely mauled this game, with a whole lot of things being left unused and/or unfinished, from areas, to skills, to songs, to artwork, all the way to an entire chapter. There's also a small debug room with a few nice features... and many, many mysteries waiting to be solved.
