At a board games hacking workshop last night (https://beesness.games) we learned about the components of mechanics, dynamics and aesthetics in games. Me and a friend hacked the mechanics of Surakarta (en.wikipedia.org/wiki/Surakarta_(game)) to turn it into a game of cooperation and swapping, rather than a game of battle and capture. We only had chance to play it once with the new rules, but it worked surprisingly well and induced more high-fiving than the original (which induced none.)
