Questions about an LG 42PC3D Plasma

I've been to Futureshop and found an LG plasma I liked. It seems good overall and I've read the reviews for the tv and they say that the tv is great and it looks good for the price. I haven't looked into plasmas much so I decided to post here and see what you guys think about the tv. Here is the link:

I also wanted to ask another question about playing videos games on the plasma. Should I be playing my xbox 360 for small amounts of time or not because of the chances of a burn in?
