I would certainly appreciate scalability for both higher end and lower end users. It's nice to be able to fly a campaign that has say... 1 flight contains max 4 planes for a slow computer, and perhaps 1 flight contains around 12 planes for a high end computer...
Otherwise people will have to fly quickmissions and set number of planes to what their CPU can handle. I think many people will decide upon wether to buy a new computer after they have tried it out a bit, to see if it's worth the PC upgrade
