In MadWorld from Platinum Games, the main character tears through a hyper-stylized black and white city and impales his enemies on a wall of spikes... five or six times in a row, puling them off to fleshy, sucking noises and then tossing them back on again in a gruesome display of blood and gore. He hurls an opponent into a nearby dumpster. The man falls forward, his upper body hanging out of the receptacle, and then the lid comes slamming down, cutting his torso in half as blood rains down upon the streets.
He grabs hold of a nearby sign post, which reads, ironically, 'caution,' and he stabs the bottom end of it through another character's eye, walking the agonized foe around the street before launching him into the air and against a nearby wall. And then he fires up a chainsaw, which just so happens to be connected to his right arm, grinding the blade into the head and then body of an unlucky antagonist. Suddenly, a gigantic dartboard rises from the street and the main character begins swinging away with a baseball bat, violently knocking foes airborne and at the board for points. "Splaaaaaaaaat!" reads a comic-book-like font as characters are sent spinning toward the giant target. This is a mini-game and it's called Man Darts. No -- seriously.
The motion-controlled maverick of a console that had everyone from age 9 to 99 swing a TV remote to bowl and painstakingly recreating themselves as Miis, had its share of hits, but even so, some titles didn’t quite get their due.

Beneath all the Smash and shovelware, the Wii really did have quite a few gems.
Not a bad list.. I would add Excitebots, Kororinpa 1 & 2, Bit.Trip series, Geometry Wars: galaxies

Keanu Reeves appearing in the trailer for Cyberpunk 2077 is far from the strangest celebrity video game appearance. Game Luster's Kate Mitchell highlights gaming's most unexpected voice acting moments.
