Square is responsible for both SaGa and Seiken Densetsu. And Game Arts are the creators of Grandia.

Enix is mostly known for Dragon Quest. Their other notable games are generally developed by separate companies whose work they merely publish. Quintet was responsible for the Soul Blazer trilogy, tri-Ace does Star Ocean and Valkyrie Profile, etc.
Ah, my mistake. And yes, I remember the Soul Blazer games as well.
