Cost-retail chart.

I was wondering if we could compile a list of production cost - retail cost for a bunch of different price points and a relatively well know game to use for comparison. I will take it all an make a chart.

I know the 5x thing seems to be popular but I don't have any point to base it on. I was hoping this will not only help me out but also make it easier for other to find out approx cost - retail for games they want to make.

Thanks in advance for any help with this.
