A river of words flowed between us.
From Ready Player One:
In the early days of the OASIS, Halliday had created a small planet named Middletown, named after his hometown in Ohio. The planet was the site of a meticulous re-creation of his hometown as it was in the late 1980s. That saying about how you can never go home again? Halliday had found a way. Middletown was one of his pet projects, and he'd spent years coding and refining it.
Middletown is also a reference to the Rush song, "Middletown Dreams," from the album Power Windows.
