Colonization: Crush Uprising Option
An annoying aspect of colonization is that the colonized tend to spam with one fake uprising after another, at all hours of the day and night, and with no risk to those who do so (if they have any idea what they're doing). As I (and several others) have mentioned previously, the last point is particularly annoying and effectively kills colonization gameplay. So here's another thought about improving/adding some risk to uprising...
Instead of waiting until the clock runs out, give suz's the "Crush Uprising" option when a colony launches one. This would effectively allow the suz to attack the colony with troops he/she selects during the uprising period and, if successful, the uprising would end and the colony would suffer increasingly severe city damage. After, say, ten or so uprisings, the city would be reduced to rubble.
I'm wide open on the nature of the damage, etc. In any case, it strikes me as a better gameplay option than what we see now on colonization-only servers.
