Thinkman, that type of quetion has come so up many times in the past, I already know SVC's answer: nobody will come to your house and take your toys away if you chop them up and glue them back together. Likewise, nobody will come and tell you to stop playing by "house rules" or burn all your fan-made ship designs. However, comma, the moment you start selling your "new" minis / SSD charts / rules without Steve's permission, you start stepping on toes and so Steve's lawyer will send you a nice letter asking you to stop.
