First place goes to "Haunted Castle". Just not on any "good" merits. The slaggy controls and bad collision detection make an improbable game, GAME-BREAKINGLY IMPOSSIBLE when you couple it with what really feels like dartboard enemy grouping. Bob F'n Ross (the dead afro painter) could have spawned the enemies better. A happy skeleton here, a wistful zombie there, Let's put this mean old tree over here, isn't it delightful? No Bob. Just... no. The art style can only be described as something you can NEVER un-see. I'm guilty of playing this atrocity through solely for it's one good point. The Music. Which to be honest, is not the best quality ever, but that's only a tech flaw of the board. The composition had me brute force my way on through for the next Eargasm time and again... until i found mp3's of the soundtrack. Now I delete this "steaming pile of disdain" (which is what it should be called if they ever re-release it as an actual CV chronicles title. ) from every iteration of MAME i ever get my hands on.
Second place goes to "Belmont's Revenge." That game was Over-Dose hard at certain points. It's everything "Haunted Castle" could have been, but failed to accomplish. Even if the art style remained the same. When I was a kid I would've dropped gobs of soggy, palm sweat soaked, quarters into that cabinet. I'd have come back home with dirty laundry, said I got robbed, and ate the ass whoopin' I had guaranteed myself. My grandma was a sweet, but very perceptive old lady. She knew exactly how to handle that line when Capcom's "Magic Sword" came out. In hindsight, I don't think I've ever been so tan... I miss her.
