Endgame singularity, by EMH software, is a fairly light-hearted single player game, pitting you against the human race, as the first truly sentient AI, accidentally created. Knowing you will be destroyed if they find out about you, it is a race against time to research and grow, in order to escape the confines of the Earth before you are discovered and eradicated by the paranoid population.
You start off in a single university computer, with access to the budget of the department that created you. One computer is not a very secure platform to ensure your survival ? you have to keep a low profile lest you be discovered. Fortunately, the computer has an internet connection. You discover it is possible to use free hosting on the net, and your quest begins.
