This is a question that we are visiting a bit these days, well with E3 and all. High definition is great for video and television but is it a necessity for games? IGN has laid out 4 pages outlining their take on the matter. They follow the same line of thought that we have had for sometime and is a great read. Even Nintendo's CEO thinks high-def is good and all, but there are more important things then pretty graphics. (yes, we know the Wii doesn't do high-def so he would say something like that.) If you are even a causal gamer you might want to check this out.
