I've never actually played that mini-game truth be told, but I got the impression that it was incredibly light-hearted and fluffy. Retainers are simply meant to be paid servants that help us by taking care of the menial tasks that we don't have time to be doing, like standing around in the markets trying to get people to buy our junk. It just seems like an insane step forward for their line of employment *laughs*

Anyways, just to be clear, I'm not necessarily against the idea since I'm not exactly worried about a Retainer's Rights Movement happening or anything, it just strikes me as something that would make more sense employing a totally different line of NPCs, similar to how you use different chocobo for racing. Though in the end, so long as they get around to employing the idea, I'm not going to fuss over how they choose to do so.
