From start to finish you just can't put it down.
Well, I'll tell you. It's better than you think, even for a GB game. So much so; that I'm actually in the process of remaking this game on Enterbrain's RMVX engine.
What I liked:
-The Battle system was unique to games for the Game Boy, as an RPG it really stacks up in combat, and blows away the previous two FF Legend games.
-The Talon was an awesome addition. A stealth fighter looking aircraft that can traverse time AND help you fight, also eventually obtaining shops AND an free INN? Amazing.
What I didn't like:
-Too many battles. Sometimes you couldn't walk two squares without encountering something.
-Detail. Or lack there of...in the remake I'm working on, I explain more of what's going on than the original, though purely through my own perspectives.
All in all, probably the best RPG on the Game Boy. Pick it up!~
