I am one of the Xbox 360 owners who DOES have an HDTV. In fact, all my of my friends that have 360's DO have HDTV. My decision to get one was largely based on the fact that all the games do play in HD. Just because EA can't make good use of the graphics to go with good gameplay, but other developers can. Oblivion isn't an absolute blast to play simply because it has super pretty hi-res graphics, but they sure don't hurt. Perfect Dark Zero looks pretty amazing to me in HD too. It's got the great classic Perfect Dark gameplay with new shiny graphics, thus I'm super pleased with it (so are my eyes. If I go back today to play PD, the low framerate destroys my retinas. Polycounts/textures don't bother me, but framerate does. It's really bad, but the gameplay is ooooh sooo good.

). Heck, for a PD sequel I would've been happy for a Gamecube sequel, as long as the framerate was greater than 10.
However, I will still be getting a Revolution. Why? Because I am confident that Nintendo can and will provide games that live up to their new controller's potential. I can't live without Zelda, Mario, Metroid, etc. Nintendo still makes great games. But those denying the fact that HD can make games much more appealing, or even provide better experiences as in the RTS example, are simply kidding themselves. It's not going to make your game, but it certainly
can make your game better.
