Just one of those spur-of-the-moment marketing ideas that probably wouldn't pay out, but thought I'd see if anyone had tried something like this. You know how things like mousepads and coffee mugs with a customer-supplied photo printed on them are often marketed as personalized gifts (i.e., a mousepad with a picture of the grandkids for grandma and grandpa)? What about a casual game with customer-supplied pictures and/or text embedded in the content? Obviously, it would be more practical to just provide an interface in the game to let the user change the picture themselves as often as they like, but as a marketing gimmick you might get some special perception of value if you sold the customer a one-of-a-kind customized version made "just for them". You would need a server and a web interface that allowed them to browse for a picture to upload (similar to Cafepress) and enter any custom text fields. The server would then generate a preview screenshot for them. Once they're satisfied and commit, the server would need to put the image/text into a content folder, build an installer using that content, and provide a download link. This would involve some work and a fair amount of PHP/CGI wizardry, but for the right product marketed the right way, it might be worth it.
