Do you think it would be enjoyable and worthwhile to frame a Challenge (on rare occasion) to use an existing game system?
Primarily, I'm thinking about a Challenge that would require the game to be made using a standard deck of 52 poker-style cards (13 cards in 4 suits). It would also allow for the use of 2 "jokers", and standard counters (poker chips, toothpicks, money, pencil/paper scoring, etc.) used in some card games.
In this type of Challenge, I would probably just pick a theme, and perhaps a single lightweight restriction.
Other existing games systems that might be interesting would be piecepack, Ice House, 8x8 board + checkers (or chess pieces), etc.
Your thoughts?
