When designing games, it’s easy to add complexity. You can always come up with yet another feature to add to a game. However, some of the best game designers would argue that their craft is all about taking things out of their games. Indeed, most games that stand the test of time have elegant rule sets. These games are easy to learn because they have few rules, but hard to master because of what’s known as emergent gameplay—complexity that arises from the interplay of relatively simple rules.
