Mac App Store version vs GOG.com version

[Anzio]

And why are the versions so different, Mac App Store still version 1.0 ? So no updates for this game? On Steam or GoG you can find newer versions.

I know this is old, but it's worth mentioning that the App Store version is 1.0. The actual installed version reads 1.0.6. Not sure if that's the latest, but remember it got added to the Mac App Store later than other stores. It's definitely not 1.0. That's just the version number they provided in iTunes Connect.
