19. Super Puzzle Fighter II Turbo
Don't let the name fool you: there's no fighting to be found here. The name, which might feel like it's several words too long, is actually a parody of Super Street Fighter II Turbo, and the game itself is a fairly standard tile-based puzzler.
Street Fighter favourites like Ryu, Ken and Chun-Li do feature, alongside characters from Capcom's other fighter, Darkstalkers. However, they're only present as background characters whose animations indicate various combos or scores for the player. Their character sprites are rendered in cutesy chibi artwork, which might be endearing to some and horrifically repulsive to others. It's another one Sony probably expects to be better received in Japan than the West.
Even if you've never even heard of this before, you've probably played some version of it. The mechanics, rules and objectives are fairly similar to the likes of Candy Crush, Bejewelled and Pokémon Puzzle Challenge. Like the latter, this one is probably more appealing if you like the characters behind it, as gameplay itself doesn't offer anything you can't already download on your phone.
