Yup. I recognize that this sort of thing must eventually run into diminishing returns, but it's still really wild to compare the old timescales to the new ones. It's especially salient with something like Skyrim to Starfield, which despite being developed by the same company almost 15 years apart, look like they could have been made within a year or two of one another. As you said, the time between 8-bit original Mario and Mario 64 was actually less than the time between Skyrim and Starfield.
