Welcome. Oh, I have to be the first to say it, I love the name of your "fun room" the "Wii Room"...
Anyway, the QS8's are amazing for home theater, however people that listen primarily to multi-channel music seem to like the direct radiating speakers (like the W3). If you are using this mainly as a HT like noted in the picture, then the QS8 model is the way to go. It won't disappoint you! I would vote for ceiling mounting them if possible so that you can get the ideal placement where you like them. You will most likely do just fine with a 5.1 setup, as most people agree that unless you have a larger room (and even then it isn't always noticeable) 7.1 isn't a big benefit.
