RetrievedSeptember 6, 2014.After I released the Reaper bot for quake, Epic offered me a job working on Unreal. After we shipped the first Unreal game, we realized we wanted to go farther into multiplayer. The bot AI I was developing gave us the opportunity to make a multiplayer focused game that could also be enjoyed stand alone, which was important at that time when not everyone had good internet connections or experience with multiplayer gaming. I was the lead programmer for Unreal Tournament, and focused on AI, networking, player physics, and general gameplay.

Sweeney and his pals at Epic realized that they could make money by granting other developers the right to use their tech. He loved it, because deals like that made Epic the money it needed to focus on making games. Sweeney's involvement in the first Unreal Engine diminished after the first Unreal game shipped. Other programmers, including Epic's bright AI wiz Steve Polge moved to the forefront ... Polge was the first programmer that Sweeney worked with who he discovered was as good as him. He's still at Epic and a big Sweeney fan since he joined the company in 1997.
