Pearl developed an innovative computer game, called Home By Myself (HBM). It was so successful that she quickly followed up with two sequels: Home By Myself II (HBM2) and Home By Myself III (HBM3). The costs of developing the games were $88,000 for HBM, $6,000 for HBM2, and $14,500 for HBM3. The production process consists of using her computer to copy the games to blank DVDs and then packing them with printed instructions in a display box. It takes longer to copy the original game than it takes to copy the sequels. Pearl can produce, ready for shipping, about 20 copies of HBM, 30 copies of HBM2, or 45 copies of HBM3 in an hour, and she normally works 8 hours per day.
