If anyone still wants Syberia 3, and wants it now, JA+/digitaldownload.com is currently selling it for 25% off -- $29.99 instead of $39.99. https://www.digitaldownload.com/syberia-3.html
The JA+ version will still have to go through Steam, and if you're OK with waiting, there will probably be better sales. But if you're OK with using a gamepad and don't want to wait any longer, it seems to be playable now according to Mikael.
I have played right through all the bugs and almost finished and now found I have left the something behind half way during the game so I cannot continue or go back as it has a stupid auto save. you cannot close the game until the wheels icon shows at the top right of the screen.
Backup your game file.
Sounds like they still have some work to do with patching.
An autosave which saves over previous saves is a terrible idea.
