Even in your case, it’s still about feelings—although different ones: you’re expressing yourself through your farm, instead of focusing on the romance. “See, myself, this is what I built! Good job, me.” and the likes.

Neither is the “right” or “wrong” emotion, mind you. But a game needs to trigger at least some within you, to be a good game. And that’s what corporations don’t get: they’re chasing mensurable things. More graphics, presence/absence of a mechanic, even gameplay length can be measured; but you can’t really measure someone’s emotional experience.
