Plundered 490 since the award came in. Taking a couple weeks off having just aged p and being on the low end of the hood for a bit.
With 100 friends and 70ish guildies, every day I have more aids than I have buildings (Contemporary Era, S-world) so I don't care if my neighbourhood aids or not.
There are two ways to stop attacks/plundering. 1) Friend Request (and have a tavern with the Red cloth), or 2) (as stated in my profile) Donate 2 FP to my arc each day you do not wish to be plundered. So far no one has gone for 2. Oh well.
I attack mostly for tower points as I'm not going to spend time hunting plunder (unless you plundered me first). But if I attack, I'm taking something that's there in this order:
1) Zen Zone - goods, FP, coin, supplies
2) Queen Statue - goods, FP, coins
3) Emperor's Entrance - FP medals, coins, supplies
4) Bazaar/Terrace Farm/Etc - good chance of FP or Goods (some disappointment)
5) Goods Buildings of the highest age there
6) Whatever's left
On my first day in a neigbourhood I make note of every player with 2 spearfighters, or lower age units to come back to for lower age tower points.
