Games in the Workplace?

Anonymous Coward asks: "Back in the day it was not uncommon for games to contain 'Escape Buttons' and other commands to quickly exit a game. These games appealed to the Geek at Work as he could fill in his Friday afternoon and as soon as he heard his boss' shoes approaching, he could escape from the third dungeon and return to his spreadsheet. Yet games today are not allowing such activities to occur. Most games are requiring so much dedicated action that it is impossible to play a game and still switch back and forth without long delays. Where are the games for the worker?"
