IMO creating interactive games for the queues was a stupid idea, because it entertains only a handful at any given time. I don't find watching other people play video-type games particularly entertaining. I love well themed queue that everyone can enjoy.
The next step in interactivity is yto do the same for rides. Originally there was a plan for the hitchhiking ghosts to say something personal to different guests. In IASW, one of the dolls would say hello to a passenger in a boat. But here's the thing, what if you are in that boat but the person being singled out is a stranger? Some people might feel slighted. Not exactly a great idea.
The interactive queues and attractions may have been a great idea, if there were fewer people in line and everyone had a chance to play, But if that was the scenario, they wouldn't need the interactive queues. I just feel that whoever came up with these ideas, had never visited a theme park. This looked good on paper, but IMO it's a failure.
