hdtv  

This is all true and pretty much common sense. However if you want to get technical.. you would want to have a tv with the the highest possible resolution which is 1080p. There are others such as the 1080i and 720p, however if you want the best you need to play on hdtv with a 1080p resolution. Just because it's an hdtv doesn't mean it can dish out what it potentially can with just a 720p resolution.

Well, if that's how a gamer would end up appreciating a game, then being a gamer simply implies a luxurious life-style. (^_^")

Not really sure on the resolution of the screen of that Tekken Six arcade but, gaming experience varies anyway, say that a game just got visually upgraded yet, the changes in the gameplay would be significant on how gamers would appreciate the game.
