My recollection is that Civilization (1) came on 5 (? 7?) floppy disks for Mac, but only the first disk was needed for the full game in black and white; the additional disks were needed for color and some add-on assets like improving your palace.
"Build a game that stands the test of time as well as Civilization" is a pretty high bar. 1.44 MB is huge.
Ironically what doesn't stand the test of time are Civ 2: Test of Time and the Civ 7 Test of Time update
