I love what the team has done with Rebellion. They have listened to my request to limit the number of pirates that accumulate and remain in the base (which built-up into the thousands over a long game), not including the ones that spawn to attack. Kudos.
But as I am a cheating "cruel" or "vicious" A.I. only gamer with this, I wonder if there could be a limit on the amount of pirates swarms a player can buy. Mid to late game, a dominate A.I. will spam pirate purchases obscenely. If there are a limit on superweapons, there should be a time limit on how and when pirate missions can be purchased. This works to my advantage when i'm TEC because effectively, an A.I. is basically buying me protection. And if i'm another race, I just have have to work to destroy the pirate base before the spamming begins, which is reasonable.
It just seems ridiculous to have a pirate attack every 30 seconds. And by the way, the A.I. seems to be getting better. Nice work.
