What is your most successful game that Dexterity Software has ever published or created? How good did it do.

You should probably pay steve the courtesy of reading his FAQ before directing questions at him in a public forum.

Will you give me the sales figures for the games you've sold so far? (http://www.dexterity.com/developer/faq-sales-figures.htm)

I'm not inclined to give out specific sales figures for any games or their particular sales rankings, but in this case I can at least say that our all time best-seller is still Dweep Gold. One good reason is that it's been out for several years (the original Dweep was released in June 1999, with Dweep Gold following about a year later). Dweep Gold still continues to sell well today at $24.95.
