Evangela is clearly meaning the FF series as a whole though, of which she is completely right (which I also mentioned in my earlier post). Traditionally in the FF series horses rarely are depicted, if they are it's virtually exclusively as either as a summon or as an enemy. People riding horses are never shown - you only ever see people riding chocobos or occasionally another exotic beast like the shoopufs in FFX.

Besides, the OP didn't even want the unicorn or magical Primal mounts, he wants a horse that he can bridle with barding like a chocobo, not realizing why that is not possible.

Because, this, is Final Fantasy - horses are chocobos here.
