Let me put it this way. My wife has no sense of anything at all when it comes to this. She doesnt even know how to turn on the Wii properly. If she can tell the difference between when i had the Wii hooked up previously compared to how it is now on the HDTV, then a difference can be seen. She made the remark that it was like going from the NES to the PS2. While not the best graphics in the world, you can notice a difference. As i have said several times now, you will notice a difference if you know what to look for. Most people wont only cause they are expecting it to be like the XBOX 360 or the PS3 and have flawless lines and that. It isnt that way. You will see some blocks and jagged edges, but that is how the game is made!
