Certainly sold well enough from what I read wonder how that's going to affect the series going forward though as I recall Sophie also pushed good sales initially which then trailed off with Firis and the rest but so far it's been a pretty good entry for the newer Atelier games even if it's starting a bit more modest and careful in terms of content and features.
Also just like that another patch was released but it's just the exe file so backing up the existing file before Steam decides to start the update on it's own should work well enough without affecting anything else, probably some smaller bugfix.
EDIT: Yep a hotfix of sorts labeled as patch 1.3a for those who couldn't start the game at all with the prior patch to the game.
- Corrected an error in which, after applying update 1.02, the game would stop after starting the game for some PC environments.
(I assume it means 1.03 but since it could have been there for some time it might have been a error introduced back with the 1.02 update.)
EDIT: Suppose this could also work for a while since Steam likes to kinda be a bit pushy on mandatory updates.

Just rename the updated exe and use this old one in it's place after naming it back to Atelier_Ryza.exe for anyone who got updated without having had a backup instead of using the Steam command console to do a depot download of the previous version.
