After I asked about what modern standards were, I realized that a way for all of us to be able to get a solid comparison would be to have an overview at the bottom of our sandbox engine list that shows what our overall average is for each category and the best number for each category (I say best because technically things like cost, loudness, build time, ect. you want a lower number). Allow the sandbox view to also sort between the different engine types or CCs and under that category display the overall average and best number. I have been using Excel and as I build new engines and save them, I enter their stats into the data and see their stats versus average and view the major percent increases and decreases. But it got me thinking that have that in the sandbox area to see how things are working out would really help me design and build more efficiently.
To expand on that, for the full game you should get the stats of everyone’s stats and show the world wide average and best. That would give all the varieties a little more balancing.
