Absolutely cringe worthy stuff even though I still put it on from time to time. First of, it seems too much of a coincidence that most of the games that reach number 1 in the charts are games like Harry Potter, Pirates of the Carribean, Transformers etc (If you spot the pattern then you shall get a cookie). Second, it also has games like Brain Training in the top 10 every week which is about a year old. It was even in the chart at the same time as More Brain Training first entered. Pathetic chart show.
I also saw a bit of the Casual Game Show but I had to turn it off when they put on Popstar Singstar or whatever it is called as it was unbearable.
Also, some of these are suppose to be "pros" but play absolutely shit. They are trying to make pro gaming mainstream by watching this crap, it will never be the case. I hear that Sky are going to be doing something similar which just sounds just as bad.
I would recommend Gamer.tv (Not the best but probably the best thing on TV just now), Consolevania or VideoGaiden if it gets renewed, Eurogamer.tv and Bonus Round at GameTrailers. Much better than the stuff at XLeague.tv.
