The Fallout video game was initially developed with the intention of using the GURPS (Generic Universal Role-Play System) license from Steve Jackson Games. However, misunderstandings led to the dissolution of the licensing agreement, which Steve Jackson learned about from a press member rather than Interplay directly. Jackson's objections were primarily due to creative differences, particularly regarding the violent opening cutscene, character design, and the whimsical style of the mascot, Vault Boy. After extensive discussions, Jackson threatened legal action if Interplay continued with Fallout in its current form, prompting Interplay to abandon the GURPS license. This decision significantly impacted the future direction of the Fallout franchise.
