Like I told Supreme, play Legend of Heroes: trails in the sky first. Personally I think it has a better story and characters though like I said it has a slow start.
Trails of Cold Steel is solid but as far as story and characters and just having that fun "adventure epic" feel, I think Trails in the Sky is still the better series.
I think you'll appreciate cold steel more if you played t*ts( ) first
How's that battle system tho
