Cliff:
By the time I buy the cards, rules etc and then print them myself, they would cost me 90 bucks in price + ink
I am not sure how you compute that price. There are a number of purchase options that are available, starting as low as $32 USD, and I will describe them for you.
The basic rules are free. The how-to videos are free. Playing aids that you might want to download are free from the rules' Web page. I run lots of convention games to give you a chance to try the rules before you invest in them.
The cards are NOT print and play. When you get cards, they are professionally printed and laminated cards. So you do NOT need to factor the toner associated with printing the card decks.
$32 option:
You can purchase four Action Decks, the Activation Deck and a PDF of the full rules for $32 USD from DriveThruCards. (The card decks are $27 USD and the full rule book is $5 USD as a PDF.) This is enough for a four- to eight-person game. (I like one Action Deck per person, but others like two people to share a deck.) You need EITHER Set A or Set B to play, not both. You only need both sets of cards if you want to play very large games. Because there are no chart cards and because the game is so intuitive once you get the hang of the card mechanic, you don't really need a printed book if you have the PDF. Some people, including me, like a printed book, so then you have the next purchase option…
$48 option:
You can purchase a full-color printed version of the full rule book from either On Military Matters or Sally 4th for ~$48. This gives you two Action Decks and an Activation Deck as well as a paper rule book. This is competitively priced with other sets of rules that include cards, such as Muskets and Tomahawks, Chain of Command, or Sharp Practice.
$59 option:
You can purchase both Set A and Set B ($27 each) and the PDF ($5). This gives you EIGHT Action Decks and two Activation Decks (you only need one Activation Deck, but each card set comes with one). It also gives you the PDF of the full rules.
$75 option:
If you want a printed rule book and more cards, you could begin with the starter set ($48) described above and purchase either set A or set B ($27). You can purchase decks of cards beyond the starter set as you feel the need to play larger games; you don't need them to get started.
$80 option:
Same as the $75 USD option but with both the printed book and the PDF version of the full rules.
Not until you want BOTH Set A and Set B and a printed book do you reach your $90 USD figure.
This has been argued many times on this forum and other fora. People think nothing of dropping $60 USD at the movies but will grouse about $40 USD or $50 USD for a rule book that -- if you like the game -- will provide dozens or hundreds of hours of entertainment.
So, if it is a "great system and game," as you said, you can "buy in" for as little as $32. USD I see that as a bargain.
