I suspect you're being downvoted because there are people who are too young/don't remember that there were a number of games available for the iPod from big gaming companies. Yes, the clickwheel iPod.
The 17-year-old iPod Video cranking out tunes on my desk right now has a really good version of Tetris on it, and one of the best ports of Ms. Pac-Man ever. Once you get used to navigating the maze with the wheel, it's a great game.
