Query posts by custom meta tags

Hello everyone, thanks for taking your time to try and assist me.

I am an owner of a video game website and I am trying to create pages that will display all posts of a specific game. I am aware that I can use tags to achieve such a result, but I want to customize the page with specific attributes.

Since I will be constantly creating new pages for new games, I am trying to create a code that will allow me to customize my query for each page, that way I don’t have to create a new template every time.

I want to display posts for one specific game for each page, so I can’t use tag=’value’ I need to customize it with custom fields.

Here is my code:

<?php query_posts(‘tag=<?php echo get_post_meta($post->ID, ‘game’, true); ?>’); ?>

The only problem is that I get this error

Parse error: syntax error, unexpected T_STRING in D:\xampp\htdocs\wordpress\wp-content\themes\RewindReplayNetwork\custom page.php on line 60
Is there anyway to work around that?
Thank you in advance for helping me.
