Rex Bradford was a game programmer in the classic Atari 2600 era. He produced games under the Activision and Parker Brothers labels. Rex is best known for his work on some of the early Star Wars games. But he is also noted as holding the record for sprites on a single line in an Atari 2600 game (that record being 13). He has recently written a book entitled Real Time Animation Toolkit in C++, and he has continued to stay at least somewhat active in the Atari community.
The following games have been credited to him. (Please /msg with any additions).
