The playstation 3 has a feature that will update the games over night, do you utilize this feature?
Finally, anyone with a modern or semi-modern Sony console that refuses to pay for PS+ based on "the principle of the thing" needs to revisit their life choices and find vastly better principles to fight for (trust me, there is a limitless supply). Again, it's that good of a deal, and FFS it's only $50 people.
