>Why is Koei spending more money on this than Ninja Gaiden 4?
That's actually really easy to explain, because Age of Calamity sold 3 million units within it's first 4 days on sale, and lifetime sales of 4 million since 2022, by comparison the top selling Dynasty Warriors game is Dynasty Warriors 3 with around 2.29 million units sold.
That's only the half of it, Koei Tecmo aren't paying to develop this game, Nintendo are, so KT assume none of risk involved in developing this game, effectively it's just free development time for their own staff as they figure out how to work well as a team, but it gets even better, KT are publishing Hyrule Warriors in Japan, so day 1 sales wise KT are making profits from every Japanese unit sold.
