Use an idler such as Idle Master to idle the game, so you have at least "played" five minutes of it. Skip to 4 if you have already done this.

Download Idle Master via Github, Extract it, find the location of steam-idle.exe in the folder you just downloaded and run in Windows Command Prompt without the quotation mark "[paste file location of steam-idle.exe here] 1675180" A window with a picture of the Steam Deck that says running if you have done this correct.

Let it idle for a bit.

Close it once you think you have idled enough.

Go to a steam store page of a game that you have NOT yet reviewed.

Open Inspect Element on the page and use console. Paste in the following script:

RecommendGame( 1675180, 1675180, "strText", $J( "#VoteUpBtn" ).hasClass( "btn_active" ), $J( "#ReviewVisibility" ).val() == 0, $J( "#ReviewLanguage" ).val(), $J( "#ReviewReceivedCompensation" ).is(":checked") ? 1 : 0, 'recommendation_submit', function() { $J('#review_create').hide(); $J('#recommendation_success').show(); }, '1_5_9__401', $J( "#EnableReviewComments" ).is(":checked") ? 0 : 1 );

6. At this point, the review is put as NOT recommended and has the contents of "strText". Customize the review. Go to your profile > Reviews > and click on the review, or replace "YOURNAME" with your steam id/name and click on https://gtm.steamproxy.vip/id/YOURNAME/recommended/1675180/.

7. You are now done! You can also add this review as a Featured Review Showcase if you would like. Here is an example of my review. https://gtm.steamproxy.vip/id/CT_/recommended/1675180/
