Thx. But still, this should be highlighted on the download page.
Latest official patches are always integrated into older games on GOG. For some newer titles they provide universal patches (new indies generally) but in general installer comes prepatched to latest version.
The version in download page is GOG's internal version number and has nothing to do with game official version. 18.104.22.168 is old pre Windows 8 installer version and 22.214.171.124 is the new post windows 8 installer. Version number on universal updates doesn't have anything to do with actual game version either, again it's just GOG internal version number. Yes, this can be confusing especially with newer games and I do hope they change it at some point as more and more new games that will require patches are bound to be added to GOG.
