Spore devs say the evolution game's previews were more ambitious than what they were actually making, and they 'built a fantasy in people's minds that was unachievable'
Former developers of Spore admit that the game's ambitious previews, particularly Will Wright's GDC 2005 presentation, created an unrealistic expectation for the final product. They acknowledge that the marketing built a fantasy of a deep simulation that the game, which was always intended as a collection of minigames, could not achieve.
