Micro Games. Those are those little games that are, like, 40 cards or less and pack a big whallop for the price. They are a fascinating puzzle for a game designer: minimal product, maximum fun. We've taken the challenge and are making one.
The key to a good micro game is to either cram a lot into a little space or have other factors, like social interaction, help fill in the gap. We're playtesting one now that has the latter. If it works, be on the lookout for artwork and more. Now, if only we can make it an RPG game with cards, too.
