EPCOF

Designed by the Walt Call, during his waning years, the Experimental Prototype City of Future was designed to be an ever-unfinished community, a model city for the world, always 25 years ahead.
  At least, that was the original idea.
  Due to the health problems and financial troubles, the project, at one point, nearly fell through, with his brother Roy Call ready to cancel the project...
  Until the TSC swooped in.
  No one knows the precise details of what transpired behind the doors of the hospital room, where representative of TSC sat near the great worker of imagination drawing his should-have-been-last breaths, but, in a week's time, Walt had managed to mostly recover and rededicate himself entirely to the EPCOF project.
  The road there was turbulent, especially with how Roy Call wanted to rededicate most of Call Company's resources to Walt Call's World, and it seemed that this would've been the end of both, but, once again, TSC (and some other corps of the time) bailed it out, at a cost of getting a greater say in EPCOF's industrial sector.
  Eventually, after several reworks and additions of infrastructure for the retirees and other things that were now-mandated, it was done by the 1968.
  EPCOF's first phase was finished.
  At the end of first day, Walt Call died in the EPCOF's park, sitting on a bench with his wife and looking over the city.
  The following years were turbulent, with corporate mergers, splits, acquisitions and layoffs, as well as UAP slowly getting some segments of EPCOF under control, ostensibly to prevent the same disasters that usually befell other company towns.
  As of today, the EPCOF might not quite be the amazing exhibit/model Call envisioned it as, but it had become something greater. It had become an actual living city, that can sustain its people.
  Perhaps that is the true achievement.
