I agree with both of these points. However, I think the Odyssey is the most interesting console to collect for. It really started the industry that we have all come to love. There are even some fun games to play. The basics like tennis, volleyball and handball are alot of fun. Also games like interplanetary voyage and Brainwave can be entertaining.
Though I do disagree about the shelf appeal. I think the Odyssey boxes, especially the games, have a unique and interesting look and the 73 games have some of the best artwork of anygame. Of course I exclusively collect Odyssey so my opinion may be a little biased
