I recently came up with a game idea that demands the use of interlocking game pieces. Essentially, there's a "shell" or a piece of sturdy game cardboard with several rectangular holes in it. Players get to add rectangular abilities and whatnot into these shells that'd (hopefully) fit in perfectly. Kind of like a puzzle.
Have any other games done this? Also, if I'm considering 25+ shells of about 5" x 4", is that going to cost a lot to manufacture? Thanks.
Sorry, but, uhhhhh, BUMP. Anyone seen this done before? If so, in what? Was it effective? Is it cost-intensive?
