I know this sounds like a scenerio, but I personally think it would be fun as a standard game option:
At the begining of the game, you have an option to activate/deactivate this option. There could also also be a slider from 1 to 5 to specify the size of the alien invasion. 1=Nuisance, 5=chances are good that the aliens will conquer every city on the planet.
At a given number of turns (400?), there is a small chance (3%?) of an alien invasion starting on a subsequent turn. The probability is incremented by 2% every five turns.
The alien AI does not putz around. It builds a good mix of units. It has only only one focus, it pursues the minimal path towards extermination of any civs it is currently at war with.
The aliens will, of course, come with extremely powerful units. Some of the units will be capturable. If an alien unit is captured by a human faction, it can be moved but it cannot engage in combat. If it is taken to a city with a research lab or university and disbanded, the player gains a large amount of alien research points specific to the class of alien unit disbanded. If the city has a research lab it provides a 50% bonus to alien research points. If a player accumulates a certain amount of alien research points for that particular class of alien unit, 2 things occur: 1.the alien tech that is the prereq for building the kind of alien unit disbanded becomes available for research, 2. any additional units of that type captured by the player can now be used in combat. Once the alien tech is researched, the human player can build the alien unit(s) permitted by the tech.
If an alien occupied city is captured by a human civ, this also generates alien research points towards a randomly selected alien tech.
Diplomacy with the aliens? Maybe. The aliens will strive to divide and conquer. The aliens are always at war with no less than one human civ. So if they finish off the only civ they are war with, they immeadiately declare war on another the same turn. Once an alien civ goes to war with a human civ, it will not make peace under any circumstances save one... the alien civ is losing very badly.
Alien city improvements? Maybe. One or two at most.
