Underplayed Gems

Two ways in, and you can use either or both. Pasting your library is the only way that brings in family-shared games, since Steam hides those from everyone but you.

1. Open Steam and click Library.
2. Click the first game in the list, hold Shift, and click the last one. That selects the whole list.
3. Drag the selection into an open Notepad or any text box.
4. Copy all of it and paste it below.

A pasted list carries no playtime, so those games come in as Not Played and you pick which ones you played. A profile URL adds playtime and pre-sorts anything you have played for two hours or more, but it only works if your Steam Game Details are set to Public, and it leaves out family-shared games.

Played games count toward your taste and your level. Not Played games sit in your Steam Library and change nothing until you promote one.
