I got the virtual playbook. I was initially unimpressed, but once I started actually using some of the things they talk about, it really improved my defense. It also has screenshots of every play in every teams playbook, which really helped me out when putting together a custom playbook of my own.
They claim it's 500 pages, but before you buy, realize that probably 480 pages of that are plays and player ratings.
Helpful? definately. Worth it? That's up to you to decide. I think it was worth it to me.
Whats the word on the virtual filmroom?
