Challenge is right! I'd never really been interested in Sudoku until I was able to play it on the DS. It just works better with a little bit of a signal when you make a mistake. I even tried one of those digital Sudoku machines, but the LCD ones are really hard to read. Anyway, I love it. Just picked up Bleach: The Blade of Fate yesterday and I've been playing it non-stop. Thing is, it's a challenge, but it's so simple to get the hang of. I just turned 28 last month so I'm not that old and I've been around technology all my life, but I have to admit. Sometimes when I get a new console game I will play it non-stop for a couple days, put it down and never pick it up because I really have to learn how to play it again. It doesn't help that every game has different controls. Call of Duty and Resistance: Fall of Man; I got both when I bought the PS3 and I couldn't play them at the same time because the controls were so different. The DS only has 2 fewer buttons than the PS3 controller, but the control schemes seem to be much more thought out.
