Appearently the developers of Atelier series decided to update these Ryza games just to celebrate the 5th anniversary. So, if you downloaded the previous versions, download this one instead. This pack contains 3 wonderful Ryza games made by Koei Tecmo and Gust. I haven't tested them by myself, but all the DLC from their respective games should be included. However, if you're still doubtful, try using CreamInstaller. Again, after you finished download, ALWAYS keep seeding. Thicc thighs save lives! Long live Ryza!
