about 1 million for Quake1, and about 1.2million for Quake2 not including console ports and OEM deals.
So there you have it. I wouldnt be surprised if Ion Storm did pull it off honestly for 1 or 2 of the titles. But 3 in a row is a bit steep.
I don\'t know if a game can sell well without good word of mouth. DK will have to be damn good.
A lot of games sell despite crappy graphics though, you never know. The 1.2 million for the Quake games is months, over a year after release though. Ion will have to wait a long long time before they see a profit.
