Bunten departed EA for MicroProse. Allegedly, Trip Hawkins, CEO of EA, did not feel that pushing production of games onto a cartridge based system was a good idea. The shift was important to Bunten, as computer games had previously been distributed on floppy discs, and a changeover to a cartridge system would allow games to be played on Nintendo systems. This was a significant factor in her decision to leave. She then developed a computer version of the board game "Axis and Allies", which became 1990's "Command HQ", a modem/network grand strategy wargame. Bunten's second and last game for MicroProse was 1992's "Global Conquest", a 4-player network/modem war game. It was the first 4-player network game from a major publisher. Bunten was a strong advocate of multi-player online games, observing that, "No one ever said on their deathbed, 'Gee, I wish I had spent more time alone with my computer.'"
