Maybe it has to do with lifestyle as well.
It seems with me that I am always on a time limit when it comes to my horse so I like to make sure whatever time I have with my girl is invested in a good ride. I do all the same things you guys do, I just do it in a working way. When I groom Phoenix I make it her job to move around me, if I am opening a gate from the ground and it opens towards us I make Phoenix back up and it is always important that she lets me go through first and comes through only when invited. I see the value of the purpose of the 7 games I prefer making the objectives of them part of Phoenix's job if you know what I mean, rather than a game that she thinks she can treat as optional.
In the course of a ride I think I do use all the 7 games, the only difference is that they are a way to enhance my ride rather than an end in themselves.
