Glad to see your post. I have a similar 65" panasonic plasma HDTV and it's amazing. However, I can't use it for gaming because of the image retention problem you mention. It may fade with time, just leave the TV on and after a few weeks it will improve (yes, weeks). Wiping only does so much (and is not really effective). I'm using a 32" HDTV LCD for gaming (instead of having it in my bedroom as I had originally planned). The picture is not nearly as good as the plasma, but no image retention worries. My advice is to buy a LCD for gaming. You've got to protect that plasma until OLED ultra high defs are available (and affordable). Unfortunately, no one is making plasmas anymore so you won't be able to replace it!
