I'll never understand how people can call I Am Setsuna disappointing. With how long I've read people on forums complain about lack of old school RPGs, they finally make one and barely anyone seemed to even care.
I absolutely loved that the whole game is set in a dark, wintery world. The OST is one of the best I've ever heard in any RPG, and it took a lot of guts to make it almost entirely all piano. The battle system is literally Chrono Trigger, plus time based button prompts, meaning it's a better battle system. Every character had interesting story moments, and all the character designs were great.
And now with the new game, you can move characters into position before you use various arts. That could totally revamp the entire Chrono Trigger battle system.
It just goes to show that a lot of people really don't know what they want. They ask for it over and over but that doesn't mean they'll even bother to play it.
Is Setsuna really that bad?.
No, not at all. It has one of the best OSTs I've heard ever. One of the coziest games I've ever played. Play it over winter break and enjoy the snowy world.
