One option would be to include written instructions with each CD that clearly states that the game has Patches, and explain what they are. Provide the buyer with the tools to understand what a patch is, and where and how to get it, and they will forever be grateful. Installing a patch is as simple as they come, but even the most intelligent person, ie my dad, has difficulty doing it. I often get calls from him asking me to stop buy and install something for him. I got tired of doing this, and gave him very easy to understand, step by step instructions on how to install something and hunt for updates for it. Since then, He has only called me once, and that was because he broke the coffee cup holder thingy on his PC. (j/k) He only called to ask me what operating system he had.

(I know just as bad.

)
My point is, if you give em the basics, and they do it for themselves, they begin to understand, and that is a great feeling. But to have an up to date CD would be nice too.
