Thanks!
Yes, the house rules for my tiles are the following:
Meepletile:
anyone who places a follower or special figure onto this tile, immediatelly recieves +1 point for every figure (follower or special figure) in his/her supply. Equivalent actions such as magic portal, flying machine, or wagon movement are eligible, however simply moving an already deployed follower onto this tile via actions such as fleeing from the plague, or moving followers from the city of Carcassonne are not.
Collagetile:
A farmer located on the this tile has +1 value for majority if its owner loves boardgames. The player with the majority on the field at the end of the game recieves +3 bonus points (one for each heart).
Microbetile:
Placing a follower on this tile opens up new options for further placement. Tiles adjacent to microbetile (not diagonally) are now elegible for follower placement, but only to an unclaimed, unfinished feature. Tiles occupied in this way extend the area of effect resulting in a potentially growing colony of followers If a part of the colony becomes disconnected from the source microbetile, or you loose the follower on the microbetile, the ability is lost. Think of it like the Plague region.
