In what seems to be a part of the official announcement for Ryza 2, the first Ryza game currently has a 39% discount across most region’s eShops, and it looks like the same 39% discount is available for the Steam version too.
Now I’m not sure if this was actually intentional choice or just a coincidence of timing, but 39 in Japanese can be read as “san-kyu” (“thank you”), and the only version that currently doesn’t have this 39% discount is the PS4 version.
