Surviving the Aftermath

Once I realized what this entailed, I realized I'd wasted a lot of time not working toward this sooner.

You need to build up to 1000 reputation with 5 societies. It isn't as hard as it sounds.

Build 3 trade centers (I didn't realize at first that you can have more than one), and constantly have them making trade runs. Start the next run as soon as the last one gets back. The KEY is to trade the ones with the gold scales symbol. Avoid the red ones. This applies to buying goods, too. Buying their items with gold scales also directly increases your reputation.

If you've sent scavengers out for fun boxes early in the game, these can be traded for a lot, and help you move this along. This is especially good since once you have enough for your entertainment buildings, you'll still be automatically collecting them.

Then it's a case of letting the trade runs play out. Personally, I stopped trading with a society once I hit 1000 with that group.

Hope this helps!
