"Kurt Busch of Krome studios also stated in a document called 'Trends for Writers in Today's Market' that the average studio development budget for an HD game is $15 million with the break even point being 750,000 units sold. Falls right in line again with other development studios ahve been saying for 2 years now. Why are you having such a hard time accepting it?"
Going by that.. the average Wii games takes 250,000 copies sold to break even
That's pretty good actually
