Tips for Designing Miniature Games
While it's tempting to just have everything shrunken to a smaller scale when making miniature games, this is not always the best way to go. That's because some parts of board games, especially the pieces, are harder to keep hold of when they are miniaturized without changing the design somewhat. Therefore, you may need to change your piece style to ensure playability at the smaller size.
One of the best ways to do this is to make the tiny pieces "knobbier" than the originals. This will provide more gripping points and keep them from getting dropped and lost.
Boards that have a lot of printed instructions should also be simplified. When miniaturized, the printing may become impossible to read. Put the instructions into an accompanying booklet instead.
With these simple adjustments, miniature games based on big ones will remain fun and easy to play.
