ARG's such as these got their start from massive marketing campaigns like
I Love Bees that was a huge national advertisement in the
HALO franchise. Players followed clues and met in the real world to solve puzzles.
Face it folks, you are going to be advertised to. If you said I had a choice between in game advertising and playing an ARG, I would always go with the ARG. Head over to the PerplexCity site today and try a warm up puzzle or two. I see many more of these popping up soon and to many different walks of life.
