N3V has a great product so why not allow expansion packs that would open up so many doors of interest in the general public,,, lets just say Military as in ground ocean land and air these packs added to TRS19 as expansions would allow like a war game sim but also using routes that people have built blowing up bridges and trains,,, this would only be one area of interest to the public and if people didn't want to buy that expansion pack and maybe instead buy a farming expansion to add to TRS19,,
What it really would do is create far more interest from a wider age group of the General public and also at the same time keep the interest in trains in general weather it be modelling or computer based games and keep in mind this would be something other sims have not done,,
Think about how many kids out there would love to fly a world war 2 plane and attack a train,,, at the end of the day if the individual did not want to have that type of game then simply do not purchase that particular expansion pack,,
