Someone tell them they can achieve the latter much more effectively if they simply charge once FOR EACH COPY SOLD.
Hmmm… but then what about humble bundle sales or freemium games? Maybe the charge should change depending on the price of the game…
OH WAIT THAT’S REVENUE SHARE. Seriusly this whole thing is just an attempt at taking more money than devs would be willing to pay, by using a model without an up front percentage.
