On the issue of Flash vs Not-Flash:
Flash is excellent for doing the "paper doll" models seen in SimBrothel, which is why I suggested stealing that idea for WM2. However, doing everything in Flash carries many other problems as well.
What I would like to see, assuming it is possible, is that Flash be integrated into the background but not used as the main interface. Meaning that a Flash program running secondary/background to the main game files, which would be used to create and update the paper-dolls & then zap these images into small jpg/bmp images that would then be used by the main game & interface. A temp directory would be needed, of course, to process them in.
So what you would have is your basic game, same interface as now, with a Flash program in another window or hidden completely. When you get a new girl, or change her outfit, etc, the Flash program would run it's paper-doll routine, apply the new look, then snapshot that look into a jpg/bmp image that & stick it in the temp directory. The main game would then access these jpg/bmps as needed. The Flash program would, of course, update & replace them, again as needed, at the end of every turn (assuming anything had been changed).
