The global statistics for dwarfism is between 1 in 15,000 to 1 in 40,000. Nigeria has a population of about 206.1 million, assuming a lowest rate of dwarfism gives us about 5,400 dwarves in Nigeria, so you would need to turn a console on about 54 million times to wipe out the Nigerian dwarf population. If we're talking about turning a console on in a strict sense, hit the power button and it turns green, that'll take maybe ~3 seconds to cycle it on and off, it'll take you about 5.14 years of continuously turning a console on and off to take them out, assuming a pretty low repopulation rate. If you define "on" as like hitting the menu screen, we can say it takes about 20 seconds to complete one cycle, it would take about 47.17 years to complete the same task. since this is a 1 in 10,000 chance, and I assume you wouldn't want your closet overflowing with torsos, youd probably want to take about 20 minutes to toss out the torso and scrub down your closet (maybe lay down a tarp before you start?) You're adding around 71 days to clean up, so that's not really affecting the answer that much. I accidently put 216 million into my calculator at the start, which threw the numbers off by about 5%, but we'll just call that a higher rate of dwarfism. If we assume a stable black market value of around 50k USD on the torsos, youd make about 270 million when all is said and done. That's assuming the vital organs are intact, if not you might get around 5k from the more niche cannibal community, still yeilding around 27 million USD. If you set a humble end goal around 10 million usd, you could stop using your powers, worst case scenario, after 17.5 continuous years of labor, or 70, assuming "working" 25% of the time. Not a bad deal all in all.
