By request of They Call Me Sleeper, here's one last Wonder Boy game until Segaiden gets to the Master System stuff: Adventure Island IV for NES. Or rather, Takahashi Meijin no Boukenjima IV for Famicom, as Hudson has never localized this one in any capacity. That's a shame, because Adventure Island IV belatedly but capably brings Master Higgins' island adventures in line with those of Tom Tom's, transforming the linear Adventure Island series into a free-roaming exploratory adventure. You know. A metroidvania. It's a fine send-off to the Adventure Island series (which would see only one more proper new entry before riding its dino pal off into the sunset), to the Famicom, and to the 8-bit metroidvania format until portable and indie games revitalized the genre a decade later.
