Um... IME, the PSN downloads are larger than the 360 equivalent. Not sure what you're on about. Also... not compressed? Baseless nonsense.
You do realise that installations require more hard drive space for temporary files, usually an unspecified quantity. From what I've heard, if you're low on space on PS3, you aren't even warned during installations and the system locks up. Not so good if you're updating the PS3...
But that's off-topic.
But PSN downloads have to be installed (uncompressed) after downloading and end up bigger on your HDD than the download size, whereas 360 games are the exact same size as the download and there's no discernable install/unpacking.
Can I install Games on Demand (ie Crysis) to a USB? And is performance running downloadable titles from USB quicker than from HDD?
