well, i think it's safe to say that gamer favorites tend to diverge as the number spot is increased. (i think we all knew this already)
i took the liberty of performing a best fit curve to the above data. I know it's only a few samples, but it's just for fun.
i assumed for #1, we have 3 favorties and for #7 we currently have 12. An exponential regression curve for this is:
Y = 2.3811 * e ^ 0.2310x
using this fit, the equation predicts there should be around 24 different games at position #10. I'll have to start another thread to verify this
