What? Casual? Have you even played these fucking games man?
Monster Party is an action platformer where you run around killing alien monsters with a baseball bat, and when you eat a pill you turn into a fucking dragon and fly around and tear shit up! And every level has about 3 or 4 bosses that all have amazing one-liners before they fight you!
Zombie Nation is a schmup in which you're a floating zombie samurai's head and shooting down helicopters in New York to save the world from DARC SEED!
Crash 'n the Boys: Street Challenge actually IS a casual sports minigame collection (back before it was hip), but made by Technos, with the same characters and fighting style as River City Ransom, Super Dodge Ball, Nintendo World Cup, and Super Spike V'Ball. One of your sports is fighting, so it's actually the first River City Ransom-styled PvP mode. There are also hurdles and swimming, but in both those you're punching each other and throwing weapons at each other, and in swimming you actually try to drown each other! If you kill the other player you automatically win!
