I specifically stopped partway through Time Swap so I could experience it properly once the mechanic was fixed, but my take was that the Age of Chivalry is to the Feudal Age as the Hyborian Age is to the Bronze Age. That is, it’s the Don Quixote vision of feudalism, not the historians’ view.
This is a very good design point! If a verb will never be useful, it can sometimes be better (imo) to disable it entirely—that way the player won’t have the wrong expectations. A lackluster implementation of a verb can be worse than no implementation at all.
One of my IFComp WIPs has no “examine” verb at all and it’s a fun challenge to write parser IF without it.
