playmeo's activity database features almost all of the activities shared in Mark Collard's books, including
No Props No Problem &
Count Me In.
Neither the books nor the activity database are intended as a substitute for the other, they are just different mediums. That said, most people prefer to join playmeo's activity database because it gives them access to many more group activities than is available in the books, not to mention, the ability to search for the perfect game plus and view 100s of activity videos.
This means it is not necessary to own the books if you have a playmeo subscription, but they are still useful to have handy on your bookshelf.
