The help file doesn't explain the newer features. Can someone provide me a link that will explain all the new stuff in the game. To give you some perspective, I last played on the original server in worlds 5 through 18.
Church should basically be the only new setting since W18 (assuming anyway that by "original server" you meant the first English server and not literally W5-W18 on the German server).
Technically army camps are also a new feature, but to the best of my knowledge, Innogames has scrapped them and decided to not add to them to any new worlds in the future.
