I'm thinking of starting a game with these three option enabled, and setting their intensity from 6-8 each. I'm interested in other players' experiences with them.
I usually use, and quite like, the Colony Rebellions at an intensity of 4. Their fighter/bombers and frigates are some of my favorite units to use in the late game: they're fast, tough, and lethal. I assume that the higher intensity will mean that there are more rebellions, and that they will start earlier. I'm also assuming that the ship caps don't rise with the number of colonies you free. I'm looking forward to a fairly hectic mid-to-late game, as I struggle to split my time between making progress against the AI and managing the rebellions.
I can't remember using Marauders much at all. I do remember that their ships were durable and had a significant range advantage over most of my ships. They can show up anywhere, and probably will at inopportune times. I can imagine them causing a significant amount of frustration for the AI as well as me.
Resistance fighters should help to mitigate the Marauders slightly. I've rarely used this option so I don't know what to expect from it. I can't expect it will make the game any harder, though.
Has anyone else had experience with these settings and options?
