As title, I have attempted to look plug ins, although not things i want.

Things I want is much like this.

Any wordpress plugin could do like this?
Otherwise, could someone let me know how you can implement this using php?

Thanks!

Produce a file known as tag.php, add the title using <?php single_tag_title(); ?> after which make use of a regular WordPress loop to show the game titles.

Update: Such as this, for tag.php:

<?php single_tag_title(); ?>
<?php if ( have_posts() ) : ?>
    <ul>
        <?php while ( have_posts() ) : the_post(); ?>
            <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
        <?php endwhile; ?>
    </ul>
<?php else: ?>
    <p><?php _e('Sorry, no posts matched your criteria.'); ?></p>
<?php endif; ?>

The reply is using Wordpress_Query:

$tag_query = new WP_Query( 'tag=' . single_tag_title("", false) );
