Did the My Sims franchise bomb?
It did well up front, but about halfway through the Wii generation it imploded and they stopped making them.
The series as a whole was about 6 million units across 6 games, but that was notably more lopsided to the games released first and they eventually stopped trying as they sold less and less.
They also gave up the Hasbro console license to Ubisoft because they found they started making a lot more money with it on mobile instead once mobile took off. Same for Tetris.
