Commercial data centers. Auto scaling infrastructure and just sheer scale. At $2 it may be at cost or a loss to generate future sales.

Recently got a switch. Digital games are same price as physical, locked to my account/switch and saves don’t move easily between devices. Steam deck, I can play on any hardware that can support it TV, PC laptop games cloud save for free. I can play online games for free. I know that games I buy today will be available in 10 years on my next PC. I only buy carts for the switch cause they give me more flexibility still not even the same as steam.
