My Game Collection allows you to import all games from the source using option '1. Auto match'.
Ideally this automatic system matches all games to the selected (IGDB, The Games DB, Giant Bomb) online database,
but for various reasons this is not realistic (wrong title, different regions, unknown title, not a game, ...). Depending on you collection MGC will
usually reach an auto-match rate of 80-95%.
By default MGC (and recommended) will use an optimal matching of igdb & giant bomb to match your games.
To get the best results for the Giant Bomb database (even in the 'Optimal' mode) it is recommended to request a free key with them. You can find more information in the settings.
MGC will remember what is already done. This means that you can import your games at your own pace, taking as much time or sittings as needed.
When auto-match has finished, you will probably have some games left that need to be processed. You can just add these games to your collection, without a link
to the online DB by clicking option '3. Auto create' or you can look at manually look at the list and steer MGC in the right direction.
This 'steering' gives you several options by clicking the various buttons and/or the overflow (3-dot) menu on a specific import item. You will see following options:
MANUAL SEARCH
This will search the online DB and show you the results so that you can manually link this import game to the online db. This will add the game to your collection and
allows MGC to download all extra information for your game.
CREATE
This will create the game in your collection using the data it found when importing. What data this is exacty depends on the import source.
MGC will still be able to download some information like Metacritic, How Long To Beat, but you will not have things like Developer, Genre, Description, etc.
IGNORE
When the item isn't a game you can just ignore it. This will not add anything to your collection, but it will be marked as 'Processed' for the import.
Add as DLC to existing game
Some import sources report DLC between regular games. MGC does its best to find these entries, but it is not always possible. This option will add the import 'game'
as a DLC to an existing game.
Overflow - Link to existing game
This is the best option to take when the game is already in your collection. This will just link this import item to the existing game, but it will NOT create a new
entry in you collection (since it already exists).
By default MGC will show you the games that still need to be processed, but you can view all games by clicking the 'SHOW ALL' button in the top right
corner on the ActionBar.
Games that are already in your collection have different options when clicked on the overflow (3dot) menu:
UNDO
This will remove the game from the collection, or unignore it.
OPEN FROM COLLECTION
This will open up the game detail screen for this game in your collection.
