I just had a major Hard Drive failure on my UK Xbox so I've invested in a memory card to protect me in the future. However, I was amazed at the difference in the sizes of my 2 saved games - Crash Bandicoot is 7 blocks, while Halo is a whopping 231! I'm buying some more games soon (maybe Splinter Cell, Timesplitters 2, Blinx) - can someone tell me how many blocks these games use up? I would like to be able to save more than 3 games per memory card! As an aside - can someone explain why the Halo save is so big (it's only 1 player saved). Thanks, Mark.
