Another analogy is a bicycle race. You could have everyone run separately and compare their best times. But by racing together, you get peloton and team effects where players can attack opponentns and support teammates, but expose weakness that could be exploited, and the success of an act, like passing or drafting, depends on how others react.
I’ve found that over time, the dominant tactics in Splendor for my group swing between build and buy. People do whatever is necessary to win. Tactics used 50 games ago go away and then get brought back. People hold grudges against others over old games, and act to disrupt each other. All of this can be predicted and folded into game strategy.
I’ll admit, it’s a little difficult to see this type of meta in most gaming groups — my group happened to be my entire office, and we played Splendor every lunch break for probably a year. That’s hundreds of games within a small group of people.
Made me think, though. Thanks :)
