I added this to the ibp skin:

In skin_Arcade.php in line 210 add this after {$rating}:

 <a href="#" onclick="window.open('{$ibforums->base_url}act=Arcade&amp;do=rate&amp;gid={$entry['gid']}','comment_edit','height=150,width=400'); return false;">{$ibforums->lang['rate_game']}

This works, but if you add the game to your favorites, then you will see the link twice.

And the rating popup looks really ugly. It should be adjusted to the thread rating of the forum. In ibp version for invision board this is looking far better. You can rate by clicking on the star icons.
