Most games then fit in 4K because ROM chips with more room than that were very expensive so this was a special game to warrant such a large programming space.

66k was huge back then. Most computers subdue didn’t have that much RAM and many computers subdue used single sided, low density floppies of 90k or less or tape players for loading games. A 66k game really wouldn’t have fit on a single 90k floppy because of disk guide overhead and other miscellaneous files like artwork or sound files.
