@Huaxiong: Oh. I thought 360 Arcade had the same games as the other versions...

It does. But you need an HDD for the more hardcore games/downloads.

Huh.......Why do you need a hhd for games?

DLC. It's not necessary, but you get what I'm saying, no?

I don't have an arcade, so I'd like some clarification.  Does the built in memory in the arcade model and the use of a memory card allow the downloading of content?  Also, how many retail games can't be played without a hd?
