there is an estimation i saw about the development cost of Breath of the Wild, at somewhere between 80 and 120 million USD. Breath of the Wild was 4 years in Development, Tears of the Kingdom spent 6 years in Development.
above 120 million for Tears of the Kingdom doesn't seem unreasonable.
Mario Movie was 100 Million.
Anyway, both are stupidly profitable for Nintendo
