I'm still not too far along in Rune Factory, but food obviously plays some sort of role in the game. Growing crops is the foundation of the series, after all. You can fish and perhaps have farm animals (maybe not) later on. But I don't seem to require any sort of replenishment except when doing work or fighting. In the console HM games you had to eat at fairly regular intervals. Is food pretty much only necessary to replenish RP for this game? If so, I suppose I could sell pretty much most of what I grow and catch, right?
