What can I say about this game? It has incredible worldbuilding, like with it's predecessor, has a fun combat system, the story really makes you interested and wanting more (hell, I've played this during and entire weekend from morning to night and I still didn't finished, and wanted more).
As an RPG, on it's on, it's a must play by everyone. 5/5 stars.
...That said, when you compare to it's predecessor (trails in the sky, and i'm talking just about the First chapter, btw) the story just can't compare. I really got annoyed by the MC, and I specially didn't liked the school setting when you compare with the Bracers setting (even more so when the class adopts a style similar to the bracers one [it is even mentioned by the characters]).
The side characters (with a few exceptions) are INCREDIBLE, have fun personalities, we see them develop more and more during the whole game, and we see them mature and change their views. Rean feels similar from the beginning to the end, and for some reason, he is always involved when something needs to be resolved (I'm talking about the relations of the classmates, not the story in general). It more or less feels like he is the center of everything. In Trails in the sky, Estelle is the main character, but isn't the center of everything. she has things she can't see, that the other companions do.
While it sounds like i'm criticizing the game a lot, this is just what I feel when I compare to my favorite game of all that, Trails in the sky. on it's on, Trails of Cold Steel is waaaaaaaaaay better than a lot of RPG's that appeared on the market.
But what about the score? Comparing Cold Steel with Trails in the sky, I can give a 4 out of 5 rating. Most of the stuff I've said isn't all that bad, but just a small part of things that I've got REALLY frustrated (a lot of stuff like this appears in other RPG's, but there I can accept easily, but with legend of heroes, It's something that stands out a lot since I know they can do better)
