Hmm, that begs a question: Can i somehow obtain the older version of Terraria on GoG, *without* using Galaxy?
Yeah, I'd like to know this too - I usually do keep an older version of game installations around - but just 1 version, and not always.
I thought they simply got rid of older installers, but if the Galaxy client can find them then why not us manual download users? Just add an expandable tab "click here for previous versions" on the download page or something, can't be that hard.
they did update it to 18.104.22.168 since release, they will update.
It might actully be more gog's fault then relogic's, but they will get updated installers.
If you want latest version you have to use gog galaxy for now.
