Nah, you're thinking of "Romance of the Three Kingdoms".
The SaGa series started on the original GameBoy as "Makai Toushi SaGa" (Final Fantasy Legend), "SaGa 2: Hihou Densetsu" (Final Fantasy Legend 2), and "SaGa 3: Jikuu no Hasha" (Final Fantasy Legend 3).
Next it was on the Super Famicom (Japan only) as "Romancing SaGa", "Romancing SaGa 2", and "Romancing SaGa 3".
Then there was SaGa Frontier 1 and 2 on the PSone, and Unlimited SaGa on the PS2.
During the GameBoy and SNES days, the SaGa series was actually considered to be Square's #2 franchise, IIRC. It's only gained infamy as being "sucky" because of Unlimited SaGa, and to a lesser degree, the SaGa Frontier games.
Edit: Interesting story: Near as I can tell, back when there was that dustup between Sony and Nintendo over the SNES CD, Square bet on Sony to win, so they made Romancing SaGa 3 as a "Play Station" launch title. When the Play Station got canned, Square had to crawl back to Nintendo and slim the game down to fit on an SNES cart, but apparently while Square was gone, Enix had called dibs on Nintendo's entire production of the latest new bigger-cart-size for Dragon Quest 6, so Square had to cut two dungeons out of the game, in addition to everything they had cut down earlier.
