No. Glare is there. No doubt about it. I don't call it glare. I call it reflection. I just don't watch TV with windows uncovered or lamps on that reflect to the place where I'm sitting. Plasma screens are glass and it reflects, even in the best of them. I had one of the original plasmas built by Pioneer. It's still working and it has the same reflective glass over the cells. The same goes for my Samsung 64" Plasma smart 3D TV. Nothing you can do about it. I get plasma because I prefer the picture quality and I watch in a dark room so reflection is not a problem.
I really don't know about gaming. However, I know it has a very limited number of connection points which may make it difficult. One of the negative comments I read on the Internet before buying this TV was that it had limited connections. That didn't matter to me, as all I do with it is watch TV and recorded movies - which it does quite well.
