I want a rule set that makes me keep pressing the start button. Age of the machine or manufacturer make no difference. I am also not worried about shallow or deep rules.
Machines that have and still make me mash the start button:
I like to keep things easy. I love the game or I like the game. I also want to give the game a good go if we have it at home. It normally takes me over 500 games or so for me to work out if I like the game or love the game.
Everyone is different and that is the beauty of this hobby. There is something for everyone.
