@PortisheadBiscuit There were tariffs put in place in 2019 though too.
Regarding the discussion about a covid boost, I would say that definitely the Switch did have a covid boost, but without it, the system likely would've still comfortably outsold the PS4. Maybe not the possibility of 160m, but probably more around 140m, maybe 150m. Without the pandemic, we likely would've gotten a Switch Pro, and several titles like TOTK & Splatoon 3 might have launched sooner. There also wouldn't be shortages due to supply chain disruptions.
