Thinking of getting an XBOX, not that into going online or anything, so think the Arcade version is probably the best option for me, and cheaper!

Obviously the memory is less on the Arcade, but what does this smaller amount actually mean?

Is it the space you have to save game progress?

If so how much can you get on an Arcade console, as in number of different game saves?

Can you get memory cards for it to expand the memory?

Any help would be great, thanks,
