Interesting numbers!

I'm slightly worried at the declining growth rate in the recent past, but I guess that will improve.
Just an experiment: if, as we assume, 1/4 of the 200,000 racers actually bought a licence, that means 50,000 licences have been sold. Seems from the graphs that ~ 1/3 of these were bought in the S1 days. Assuming that half of these again upgraded to S2, the LFS team should have gotten about 1,1£ in total income. Let's say 1 million, then. So in the 5 years since the first release, each of the three developers should have had an average annual income of somewhere around 70,000£. Not too shabby.

But of course they have to pay for all kinds of development related stuff. So I guess we could safely cut that figure in half.
