The room interior development is increasing LOC fast, it's now over 45 000 lines. Room interiors are interesting and fun to create, because there are lots of options to add in any room type and you can really start to think where all those game objects you invented earlier can be used. I have the basic creation tools ready so it's also quite easy to work with rooms. There is a lot of source code needed for special rooms like shops and other more complex types. However I don't want to limit my imagination here but create all the room types no matter how many is required.
