I usually miss invasions when I'm helping other races colonize moons (3 months) or broker trade routes (2 months). It's even more ironic if I was trying to broker a trade route with the race I was invading.
Got the 8-man federation done tonight, on attempt #5. Thoraxians starting with the Mire meant I only had to keep the Burlust down. The Thoraxians did try to attack a bunch of people, but they never launched a ground invasion due to their awfully low population (at one point, I actually had to go help their medical RCI so they'd stop dropping below 1m population).
Some observations:
- "Expand Usable Land Area" is the single most profitable dispatch. Whenever I see a race with a gas giant, I start jumping for joy because that's basically insta-credits. Like smuggling, pirate base whacking and slavery, it's a limited use resource, though. On top of that, you get a little bonus influence, and it's something you can do even for races that you don't want to really help, because it takes them a while to fill out that land capacity. Gathering space junk is similar in profit, although do you really want those armadas coming out faster for that particular race?
- I followed the advice to build up ground combat tech, and also gave everybody free ion cannon blueprints. Avoided giving space combat tech to the aggressive guys.
- Started with the "Federation for Safety", then brought the Acutians in via 200-influence vote (it took a lot of tech gifts). It's critical to have one of the Skylaxians, Acutians or Andors trading with a lot of people early, as they can "convince other race to join federation", and it saves a lot of time and credits to have those 'race relationships' built up. Unfortunately, Boarines and Burlusts are anti-trade. Sigh.
- Burlusts eventually came to heel once I had enough members and was able to intimidate them into joining. I let the Thoraxians and Evucks (some kind of combo!) get them down to no armadas then killed the leader and THEN killed the attacking armadas. That way, their rage attack didn't actually do anything. After which I even built the Burliest a couple of free ion cannons. Aren't I a nice guy?
- The rest (Boarines, Evucks and Thoraxians), I had to "improve relations" and then "convince to join". However, my federation members all had super strong navies at that point, so I had the time. It was kind of funny, there was a never-ending furball going on above the Boarine homeworld, where it seemed like every race would just randomly send raiders, skirmishers and whatever else to shoot at each other. A little weird, but fine since it generated a lot of scrap metal that I could turn into credits. With the Boarines, I had no patience to wait for a mood switch (and didn't want to deal with assassination and rolling the dice on the next mood... err.. priority). With the bugs, I didn't have the goodies to get them up to 400 influence for the "join existing federation". As for the Evucks, they were already at ~180/180 with the Acutians by the time I targeted them for federation inclusion.
- I had to bail five of the races out from near extinction. The poor shmucks kept getting into "below 1m population" territory, so I had to keep an eagle eye on the event bar and pause button while doing dispatches. Thankfully, the "recently" revised RCI-related dispatches made it actually possible to bail those guys out. It's a little scary when there are a few non-fed races out there, all at near zero population and none of them like each other.
- The andors seem to have a "delayed reaction" in their election cycle. Seems to take about an extra month for the next party to take over. I guess what I'm saying is, don't abandon your construction project just because you think they've done an election.
