Loop through related section's entries I have two sections:
games
publishers

For example, a games entry title would be "Mario Brothers" and a publishers entry title would be "Nintendo"

On the entry page for Nintendo, I want to display all games (entries) they published.

The "_entry,html" page for publishers right now only has the following code:

{% extends "_layout" %}

{% block content %}
    &lt;article&gt;
        &lt;h1&gt;{{ entry.title }}&lt;/h1&gt;      
        {{ entry.body }}
    &lt;/article&gt;
{% endblock %}


So I know I need to add it after:

&lt;/article&gt;


In the games section, I have a field called "GamePublishers" set to type Entries. So I assign the publisher of a game via the admin cp. Wasn't sure if I need to also setup a field type entries in GamePublishers to reference to Games section. (If that makes sense)

Thanks

Not necessary if you already have a "GamePublishers" Entry field in the "Games" section.

Something like this should work:

{% set games = craft.entries.section('games').relatedTo(publisher) %}


That's assuming you've already got a variable named publisher defined that's referencing the current publisher the user is viewing.

I'd suggest reading through the relations docs as well.  Craft has a pretty powerful relations engine you can do all sorts of crazy stuff with.
