I don't know why people are discounting spin-offs and OP never specified to omit them ...

There's at least 1 game that I can name in every game franchise aside from maybe some Valve owned IPs that will show a low point in a series ...

Never specified not to make the distinction either. Seems rather silly to consider Super Mario Bros and Mario Kart the same franchise, for instance, given how different they are.
