mcneill started developing adventure games using the quill software. initially, these were sold by mail-order under the delta 4 brand, before publishing deals with crl and silversoft brought the titles to a larger audience. this led to mcneill working with terry pratchett to create the first discworld game and, later on, adapting "murder off miami" by dennis wheatley. after an affiliate label deal with activision, mcneill set up a new studio for sci in southampton, focusing on pc games. while there, he oversaw development on movie tie-ins including "the lawnmower man", and scripted the award-winning "kingdom o' magic". he also co-produced (and provided the race announcer's voice-over for) stainless software's controversial racing game "carmageddon".
