Couple of problems that I see with the game.
Asking people to print off a picture to take a picture probably isn't a winning request and, even if they did, posting it here rather than in the photo section probably won't win many advocates either.
There are only a relatively few that play the "games" on a regular basis, so your potential source for participants isn't too great. Usually the game is better if it's one a person can drop in on any day and make a post and move on. Then later the same day or within a few days come back and make another post to the same forum.
Having a person do something creative just to make a game post isn't going to attract a lot of attention. We've had games that have asked others to "make up a few lyrics" for a "song" ... not much luck. The person doing the game maybe posted quite a bit, but almost no one else. Best games are simple and require little or no "extra" effort to make a post and that encourage frequent posting.
Those are just my views and kind of what drives me to play various gaming threads. Maybe some of the others have other thoughts. This isn't a complaint about the idea and it possibly could be cute ... but ... I think it takes just a little too much work to make a simple post.
I do think it's great when people come up with new ideas ... and try them out. Don't get discouraged. I'd check other threads that have been posted to a lot and see what made them "easy to post to" and consider trying something that fits that style. Some will be winners and others maybe not ... but part of the fun is looking for that winning idea.
