Who wants to tell which is his favorite tileset theming? If he does, people can make a level in the most voted theming from the people (except if it is "Other").

Castle, Forest, Heaven, Hell, Industry.

Castle can be classified so:
Past; Dreary/Grim; Artificial Wonders

I know, but I was overquick and didn't notice it was a multi-choice poll.

I dearly want some tilesets that focus on Mechanics, lab settings, computers and industry.

I also want another space-station-themed tileset

A city set mixed with a tropical / arctic tileset... ;P

There are one or two tilesets (maybe not on j2o...) which have a seasonal theme. Basically, the tiles and backgrounds are repeated four times, one for each season. Can allow for some pretty interesting level design, using warps to "change seasons" or something like that.

So in that way, you could probably mix both a warm and hot theme in a way that actually makes sense.

Space is the motha(-)(-)(-)(-)in' place, man.

Nature tilesets, so awesome

Well, several people here seem to have a passion for technologic tilesets, as the poll says. Second place for the city places. I bet they would find good into a hyper technologic metropolis, maybe, a gigantic TSF tileset with hundred places. I would also like it.
