Dead Rising for the Xbox 360, like any other game for the Xbox 360, can be played in SD or in HD. The user hooks up their display to the Xbox 360 and the Xbox 360 will put out 480 lines or 720 lines of resolution, depending on your needs.
The Xbox 360 was made to be a relatively good high definition game console, but does that mean they should leave us standard definition gamers behind? Well, it looks like the creators of Dead Rising thinks so, as if you don’t have a high definition television you wont be able to read the in-game text. No instructions and no conversations leading to no will to play the game.
I would love to buy a HDTV, but I have to wait until I can afford a decent LCD one, as I don’t want to get another heavy TV tube television. Sad though that Capcom did not think about us poor standard definition people.
