ANNOUNCEMENT:
Version 7.1.5 has been released with the following features:

* Added a new scope: "Demos"

ANNOUNCEMENT:
Version 7.1.6 has been released with the following features:

* Added internal support for games that are regionally blocked in South Korea (currently Master of Orion: Collector's Edition [In Dev])

* Split a region being monitored for regional pricing into five: "Latin America (MX)" into "Most of Latin America (AR)", "Chile (CL)", "Colombia (CO)", "Mexico (MX)" and "Peru (PE)"
*** Note: The reason for this is that "Master of Orion: Collector's Edition [In Dev]" has a different price in each of these regions.
*** Note: In the event that you had a saved profile or search filtering or sorting for "Latin America (MX)", it now filters or sorts for "Mexico (MX)".

* Cleaned up the file titles of quite a few "Downloadable Files", removing rather unnecessary references to "Original Game" for games with DLC

ANNOUNCEMENT:
Version 7.1.7 has been released with the following features:

* Added IAmSinistar's "Regional Locked Games on GOG" GOG mix to the Gogmixopedia display and filter

When MaGog updates "wishlisted by..." for each game?

Every time it runs, which is about every six hours or so (depending on GOG traffic load).

If you go to the MaGog home page, you will see near the bottom of page, in red, something like "The current database was last updated about 4-5 hours ago". Some time after it changes to 6-7, it will change to 0-1, which means the database has been updated.

P.S. The hour numbers don't change dynamically, you need to reload the page to see whether they changed.

Thanks for the info. :-)

Guys, I'm too dumb I think... I just want to get a list of my owned games in some text format, and I can't realize how to do it in Magog engine. I push "GET FROM GOG" button but it seems it doesn't save anything.

Won't be in some text format, but, well, read the instructions. Click that link and that leads to a .json file. Download that and then open it in Notepad or similar, or open it directly the option is offered and it's viewed as text, and that's your list of games in the format GOG provides and MaGOG reads. Then copy all of that in the box provided. Keep going for wishlisted titles, answer that question, click Go, let it do its thing.

Then to see the list there you filter it by "my tags" and "owned". And if you only want the game names, you deselect everything under display. Then you can copy that output in a text file I guess.

Unless I missed something.

As Cavalary explained, the "Get From GOG" button opens a page (this one). You need to follow the instructions on that page (looks a lot longer than it really is) in order to import your owned (and/or wishlisted) games into MaGog. Then, once within MaGog, you can do pretty much anything you wish with this information (e.g. get the list in HTML format, which should be easy to convert to plain text).

The short version:

To get games:
1) Click here: http://www.an-ovel.com/pages/ma_owwl.php (we'll call this page #1)
2) Click here: https://www.gog.com/user/data/games (we'll call this page #2)
3) Copy-paste everything (Ctrl-A, Ctrl-C) from page #2 (lots of numbers) to the upper text box (Ctrl-V) in page #1
4) Scroll down page #1 and click "Go".
5) Click OK as needed until done.
Now you got all your games in MaGog. You will want to repeat this when you buy new games.

To display list:
6) Click here: http://www.an-ovel.com/pages/magog.php
7) Find the row called "Profiles" and click the button called "Default"
8) Find the row called "Display" and click the button called "Clear All"
9) Find the row called "Filters" and select "My Tags..." from the first menu (one of the last options)
10) Ignore the second menu and select "owned" from the third menu
11) Click "Search" (top left corner)
12) Results will open in a new window/tab
13) That's it

Good luck.

That's what I couldn't find out - how and where should I attach tags and what "Search" button (of two) should I triumphantly push... :)
Now it's done. God bless you, good sir (or lady - can't get it from your avatar and nickname:)).

Two search buttons?
*checks* Oh, you mean the fact that that row of 4 buttons is repeated both above and below the search settings? Same thing either way.

Well, I was jocular saying I'm dizzy of many English words there :) I was rather dizzy of too many checkboxes and submenues. Maybe this wonderful tool could be slightly more streamlined (IMHO entirely)?
You could contact Stardock - the slick GUIs is the only thing they've learned to do well in PC gaming ;P
