Hi all. Just wanted to ask about HDD space on the X360. I'm aware that the OS and arcade games and demos take up some space and some savegames but would it really take 12 GBs?

The OS and other essential files take up 8GB of space. Those 4GB are installed (and removable) demos and videos mainly.

When I bought my 20GB Xbox 360, it had only 12 GB left.

K, thanks for that
