slow internet speed user here i recommend once you've finished downloading it, tell steam to do a backup.store all your steam game backups on an external hard drive(or burn them to dvd,print off a nice dvd case cover and put it on your shelf),then you can just do a restore from backup and save yourself downloading the whole thing again, steam will only have to download the relatively small updates that have come out since you made the backup.also good if you have monthly bandwidth caps like surprisingly a lot of people in small towns or remote areas still do. keywords: slow internet, bandwidth caps, steam backup & restore, retail vs download,
