I remember playing an RPG on the SNES that (if I remember correctly) was a ton of fun. However, the only thing I remember about it is that at one point you go see a farmer in the desert who tells you he's having problems. A boss battle ensues, and you fight against a huge sandworm.

It sure as hell ain't a lot to go on, but if anyone knows the title of the game, lemme know.

only thing that springs to me with a farmer and rpg on SNES is Harvest Moon

Unfortunately, it's not the game I'm looking for .

Is it the Secret of Mana?

Breath of fire ?
lol i did a search on google for "Sandworm RPG snes" and that was about the only game that came up that was actually out for the snes

Phantasy Star series?

Yes! I'm sure that's what it was! Breath of Fire! Thanks guys .
