Dealing with Plunderers
A bit of advice. Plundering is explicitly within the rules, is encouraged by INNO, and is a viable, successful strategy. Don’t get upset, just take these steps and you will reduce your losses to a minimum.
COLLECT ON TIME. Set your production to finish at a time you know you will be on to collect. This is the most important step you can take. Many plunderers will stop attacking if you do not give them anything they can take.
GET YOUR BUILDINGS MOTIVATED. Switch to 24 hour production, AND reduce decorations, AND increase your friends list AND Aid everyone every day. Motivated buildings can not be plundered. By doing the four steps your houses, supply buildings, and other motivatable buildings will always be motivated. Triple bonus from this: 1) if you miss collection, no big deal, your production is safe until you can collect. 2) Your coin/supply production will go up! Motivation, besides stopping plundering, doubles production. 3) You only have to collect once a day.
PUT UP YOUR BEST DEFENCE: The more units you kill, the less often plunderers will attack you, they will target easier prey. Watchfires, monastery, Deal Castle and St. Basils help with defence.
GB GOODS CAN’T BE PLUNDERED. Babel, Lighthouse, St, Mark’s, Frauenkirche, Royal Albert produce unplunderable goods for you. Note that the special event building Wishing Well also can’t be plundered.
TRY DIPLOMACY. Ask plunderers nicely to stop. It may work. If they want to be paid off it’s up to you, but I’m not a fan of blackmail, giving or receiving.
