I like the style of the current work in progress and will be putting them out shortly once there's enough in them that I'm satisfied with. The image is from the hospital tile set, and I've started work on homey interiors. They're going to release them in individual sets, then made into bundles by era, since I do want to make more than just modern tiles. 

There isn't really an ETA on these, but the home tiles should be done in a month, and the hospital tiles are more or less done, I'm just trying to fill out D sheet with little odds and ends. All sets will include sizes 16x16, 32x32, and 48x48, and will receive updates to add more sprites based on any suggestions from others, or ideas I get.

Side note, the home and hospital tiles are being done first because my current project requires those sets, and what sets get released may or may not depend on the games being currently worked on.
