| Intellivision |
· Russ Ludwick (programmer) tested the program by playing countless games against the cartridge at all levels. He found that when playing at the highest levels, the cartridge was good, but slow. He got in the habit of making a move, then going home and letting the Intellivision think about a response overnight. Because of this, three features were added: (1) the normal Intellivision time-out feature was disabled, (2) a feature letting you switch to an easier level in the middle of a move was added, and (3) a warning that moves at higher levels could take hours, or days, was put into the instruction book. {BSR}
