Nobody recommending Wild Arms 1 & 2? They're both very enjoyable games with some fantastic music to them. My only beef with 'em is how the battles tend to move slower than most games.
If you're a fan of action RPGs, I'd recommend also trying to get a copy of Legend of Mana (not as good as Secret of Mana, but still fun) and Threads of Fate. ToF is a really fun game with two different playable characters (and slightly diverging storylines) that runs off the same engine as Musashi. Most people didn't like it as much, but I still thought it was the best game that came out during Square's Summer of Fun (or Adventure or some BS like that).
