The example I always go to for oddly unsuccessful games, (good at least, I don't know about excellent,) was Super Monday Night Combat. It was something like Valve's Deadlock, a 3D MOBA game more than 10 years earlier, with a bit of The Finals aesthetic. (Coins, instead of blood, gameshowy, announcers quipping over the gameplay.) I had a lot of fun with it, but it seems like hardly anyone noticed it existed. They never got the critical mass of players needed to keep it going.
