My Take
The students like the game type format. Some do have trouble with working the Share Jumper game. I do think you need to do more with the games than just play them if you really want to teach the concepts.
How I Use It
I use these in conjunction with some of the regular Common Sense lessons. Sometimes I use to introduce the subject, other times as a reinforcement of a concept. I also use the student workbook pages to help reinforce the information.
