Huh. I must be odd. I totally don't mind bait and switch.
I mean, as long as it's done well, it's fine with me.
Of course, there would be huge potential for it to be done really badly and become annoying, but I really trust my regular group, so I don't think it would be obnoxious.
For a stranger group game I might be apprehensive.
I agree. Honestly I'm kind of surprised that the primary reaction to this idea was to think of it as "bait and switch". If I were a player in this scenario I would love it. Done well, I would find it incredibly immersive.
