WeGame RSS Generator [w/Code]

[saintg]

I'm not sure about you, but our guild loves WeGame. Mostly because our work's security hasn't blocked it yet, and its a nicely setup site. The problem with WeGame is the lack of an RSS feed. With that, you could quickly see the updates, and if you're a geek web developer like me, integrate the latest, most popular, etc videos into a slice on your guild's home portal (which I'm about to do). I have a hard time finding exploits and am not the top notch at writing WoW guides, and so I'll support this site where I can.
To the point, I wrote a quick parser (62 lines) that generates an RSS feed for WeGame in the WoW area (code below). You could easily expand/redirect this to handle any/all of the games they offer, by changing the urls around. Also, note that I'm pretty new to PHP, and so if there is a better way to do something, let me know please
Example: WeGame Feed - popular
