Input: Consider Input: Question: What was the first game produced by Bullfrog Productions? Passage:Peter Molyneux founded Bullfrog Productions in 1987, which was later acquired by Electronic Arts (EA) in 1995. Around 1996, Molyneux had contemplated leaving Bullfrog, as he felt limited in his creative freedom under Electronic Arts. He along with Lionhead's eventual co-founders, Mark Webley, Tim Rance and Steve Jackson, started developing plans for a new studio. In 1997, due to a series of events and from issues arising between Molyneux and Electronic Arts, he ultimately left the company in July 1997, co-founding Lionhead shortly after that, along with Mark Webley, Tim Rance, and Steve Jackson (who co-founded Games Workshop and co-authored the Fighting Fantasy series). On his recruitment, Jackson said "It was an offer I couldn't refuse", as he wanted to get back to making games instead of writing about them (Jackson had interviewed Molyneux about Bullfrog and Dungeon Keeper, but for much of it, they discussed German board games instead. This led to them meeting frequently for an event called "Games Night"). Molyneux assured him that his lack of programming knowledge was an asset rather than a problem. Lionhead is the second Bullfrog break-off group, after Mucky Foot Productions (founded in February 1997). According to Glenn Corpes (who co-founded another: Lost Toys), Lionhead was Molyneux's "take on what Bullfrog used was".
