Hi there ! I played almost every version of The Headmaster since its launch, but never tried the Mycock's Manor version. How does it work ? Is it a sequel ? A side game ? Should we finish The Headmaster before starting Mycock's manor (I remember the guy) ?
It's a side game. Basically it's a Patron poll looking at clothing options, girl choices etc., but wrapped up in a little story. So you get some nudity perhaps (I don't remember any sex scenes for the Headmaster though), and with outfits, you get to see them "in action" rather than just a couple of posed images that might not look quite the same in game. It means you don't have to play them, but also that it doesn't matter
when you play them, if you do.
I don't really pay attention to them, but I guess if you want to immerse yourself in the lore of the game, they can give you a bit more background info. Plus, of course, they give you the advance insight as to what you can expect to see in the main game - so Sally's new outfit, some of the cafeteria changes, etc., have been implemented in the main game after appearing as choices in one of the Mycock "side games".
