I think you can get a new GT6 disc for $10-$15. It seems like the newer PS3 discs crack easier than the old ones. I've gone through 2 GT6 discs since 2013 and I've had the same GT5 disc since 2010. NBA 2K12 freezes, 2K11 doesn't. Burnout Paradise from 2008 works fine, NFS Shift 2 from 2013 cracked.
Also remember to do the registration form for the kart races. I did mine yesterday and made it into two heats to help increase the chance to get in a higher class.
And does anyone know what 14:00 UTC and 23:00 UTC equal in EST?
