I believe that what is happening is the \.php$ location is matched
first, so your rewrite rules are never called for PHP scripts. See here
for the order Nginx processes locations:

http://nginx.org/en/docs/http/request_processing.html#simple_php_site_configuration

Specifically, the sentence "The first matching expression stops the
search and nginx will use this location." The / location is used as a
fallback in case no specific regex location is matched.

Instead, something like this might work (untested):

location ~ \.php$ {
rewrite ^/game/(.*)/(.*)\.php$ /index.php?act=Arcade&do=newscore break;
rewrite ^/play/index.php$ /index.php?act=Arcade&do=newscore break;
rewrite ^/(.*).html$ /index.php?params=$1 break;
fastcgi_pass unix:/var/run/php-fcgi.pid;
}

location @gss {
rewrite ^/game/(.*)/arcade/(.*)$ /arcade/$2 last;
rewrite ^/play/arcade/(.*)$ /arcade/$1 last;
}
