Definitely Binding Blade, though I still like it. Blazing Sword came out when I was 12-13, and considering its proximity to The Return of the King in 2003 there's just no way I can disavow it. Sacred Stones offered up a lot at the time with branching classes and nonlinear grinding. I think Sacred Stones is actually the first game I ever imported, ca. 2004 or so. FE6 has a banger of a soundtrack, at least.
