When I read those things I always assume they're talking about megawatt hours.
Considering that the average american home consumes a little under 1000 kilowatt hours a month then the math starts to line up.
1000 KW hours is 1 megawatt hour. 1,000 megawatt hours is 1 gigawatt hour, so 1,000 months, while being a bit shy of 100 years, is still 83 years and change.
It also means that companies that would release a tight and cohesive 15-hour game will instead release a jumbled sloppy episodic 150-hour mess to pad their pockets.
It would mean worse games coming out that cost more money
I don't know, I remember being a kid and hearing my mom complaining about some game needing like five floppy disks to install.
My childhood computer had 80 MB of storage on it and 15 of that was used up by the operating system, so I guess installing a 9 MB game was actually pretty taxing.
