Sometime before Duke Nukem Forever. 
(And yes, I know DNF is finally dead and buried, so it will be a cold day in hell when Diaspora is out.)
There are small differences between Duke Nuke Forever and Diaspora.
1. On the Diaspora team work people who actually care about the stuff they create.
2. The Diaspora team didn't play the "lets change the release date game" with the community.
3. There is no cash involved, they work of their free will and to the best of their abilities to complete the game
- rumors about dark rituals involving black magic to force the folks to work on the project are just that - rumors4. In the unlikely case, that the game wont get released, the community will find them and beat them with sticks made of cherrywood, wrapped in papers with quotes of Derek Smart...and burn them on the stake...and eat their cats and/or dogs... and steal their cars
