My Pet Protector: Adventure!
Old housemate Griddleoctopus pointed this at me. It's My Pet Protector, and he's brought it to my attention because he spent many an hour watching my oddball Princess Maker obsession circa 2003. This is basically a clone, and - exactly like Princess Maker - yet more testament to the sometimes-a-number-getting-bigger-is-enough school of game design. The main difference is instead of training a girl, you're training a boy, so the frankly enormo-dodgy starving your daughter so she can wear the best dresses elements are gone. And there's no option to feed them breast-expansion pills. At least, not so far, though I'd imagine it'd teach any son some valuable life lessons.

Wait - what am I doing?
