Hey. I wrote a game review and want to edit it.
In the website it took me about 15 minutes to FIND how to write reviews, and after more than 20 minutes I can't find how to edit written reviews. I use Galaxy 2.0, but the app doesn't take reviews into account, It links all accounts, so that's fair. But can I edit my review on the website?

Surprisingly, you can't. If you really, really want to change it, you can contact Support and ask for it: https://support.gog.com/hc/en-us/requests/new?form=account&product=gog

Wait for the game to be removed from the store and eventually come back, so you can write a new one!

Judging by your username you may know the game - CivCity Rome. I don't really care all that much, but I just wanted to be sure I am not missing something. Is that possible to happen?

That user was likely being a bit silly, but that has happened to at least 5 games I know of/recall this year alone.
