Game franchises have become far too formulaic. They may look better these days, but all games come from basically the same genes. One could argue that without Pitfall, there would be no Uncharted 2. Or how without Pong, there would be no Geometry Wars. Granted, these examples demonstrate huge leaps in technology, but nevertheless, the originals were the seeds laid early in the fertile ground that have grown into the games that you love so much today.
