Bethesda's Pete Hines has confirmed that there will be no demo for Fallout 3.
Speaking exclusively to Eurogamer in the shape of Kieron Gillen, Hines said there was "no way" to slice a portion of the world off and have it stand on its own.
"When you build it as one thing, there's no way to portion off a section and have it stand on its own without putting the whole game in the demo, which we're just not going to do," said Hines.
"And it doesn't really capture the fun of a game like an Elder Scrolls or a Fallout, where you can go where you want and do what you want. So no demo, sorry."
Fallout 3 is a post-apocalyptic role-playing game aimed at a mature audience, and will be out on PC, PS3 and Xbox 360 this autumn.
Like previous behemoth Oblivion, Fallout 3 will also feature some famous voices - Sean Bean and Patrick Stewart starred in the former.
"We pick out key roles for people and who we'd like for those roles, and we always thought Liam [Neeson] was the perfect Father figure," added Hines.
"We have one or two other roles which we have for which we have things in mind, but the bulk of it - and we have a lot of voice-acting in the game - is done by voice-actors."
