*looks at sales data for Octopath*
For a brand new series, Octopath 1 sold over 3 million copies as of 2022. Octopath 2 is over a million.
Triangle Strategy is over a million in 2022 as well.
If that is what new series can do, FF going back to that style should sell gangbusters. Dragon Quest 11 is over like 7 million copies sold?
