Personally, it baffles me that, in almost a centennial, there has never been a Popeye beat' em up game, the likes of Konami's classic arcade ones.
Seriously, punching people, monsters and whatnot is what he does best! It's such a perfect fit, but nope, the closest we've ever got, as far as I remember, is some crappy Amiga or DOS game where Popeye fights aliens, and it was just an awful game.
Now that he's become public domain, I wonder if someone would get down to do him proper justice with a good brawler. Imagine like "Cuphead meets Final Fight/Streets of Rage", with Popeye travelling through stages based off his more famous shorts, beating the crap outta whoever gets in his way, lol.
