Your argument is very constructive with logical, with well thought out ideas, I will give you that.
But with this particular game, you will always meet resistance with your aforementioned arguement, and I think the core reason why is the developer of the game, Scavier.
The name Scavier is a composite of the three people who have made the game from day one: Scawen, Victor and Eric.
Three people.
Three people, not, like some large corporate games, 300 people. These few have lovingly crafted this simulator, and are not rich money wise, but rich with the dedication of their followers who invested in their project, the S2 users. We, who have bought licenses, have invested in this game, and thus, have a vested interest in the development of the game. To be a demo user and suggest getting more content is, in a roundabout way, an insult to the people who have put forth money to see this game through.
