Site Address (URL)
Enter the address you want people to type in their
browser to reach your WordPress site. This is the directory where
WordPress’s main index.php file is installed. The Site address (URL)
is identical to the WordPress address (URL) (above) unless you are
giving WordPress its own directory. WordPress will trim a slash (/)
from the end. If you defined the WP_HOME constant in your
wp-config.php file, that value will appear in this field and you will
not be able to make changes to it from the WordPress administration
screen.

1. Either change Site Address (URL) to: http://localhost/newgameplus/wordpress
2. Or copy index.php into localhost/newgameplus and change require('./wp-blog-header.php'); to require('./wordpress/wp-blog-header.php');
