Lionel is more than welcome to develop a commercial product to run DCS engines and pay licensing fees to do so but will they?
Can you say with certainty that MTH DCS would be happy to license DCS? I am asking because the one person who could have answered many questions about this @MTH RD has gone AWOL from the discussion. So to be clear, someone at MTH DCS told you that they would be willing to license DCS to Lionel?
