Wow Daniela, sounds like you do have quite a situation on your hands. That's the point I hope I never reach, where there just is NO solution to the problem anymore and I end up hating my beloved toys. I'm shooting for the goal of keeping my purchases low enough that I don't anytime soon have more playmobil than can be enjoyed in one large bedroom. If I get past that point, I think I will start feeling choked. So I'm making some difficult choices right now, about themes I am not going to collect anymore, or not going to start on. It's really not easy, though. I love almost everything playmobil produces. And my real problem is, I don't have one large bedroom for my playmobil yet.

So I have some displayed in our bedroom, and I have a closet devoted to storing it, but the collection has already outgrown the closet.
Anyhow Daniela, I think you are probably doing the best thing, just taking a break for a while. One day the mood will probably strike you once again to start organizing and enjoying your wonderful collection again!
Well the thing is, buying new playmobil is not needed to keep enjoying playmobil. Can always focus more on what you have and work with that for a while. 
Yes, and sometimes you must do that for a while. But in general a minimalist approach may work for what you like to do with your playmobil, making stories and all, but it doesn't apply to everyone depending on their purpose in collecting. For me, what I love to do with playmobil is build dioramas, as realistic as possible. That's what I really get pleasure from and is the whole reason I started collecting. My main theme is the zoo of course, and I'm sorry but it wouldn't be much of a zoo with only five or six species of animals. So to make it worth having any of it in the first place, takes a lot of animals, lots of fencing, scenery, plants, zookeepers, visitors, etc. To me if I don't make a realistic zoo, I might as well not even make one. So having just a few klickys and a couple of buildings, isn't going to work for me.
