I love game supplements. If there’s an expansion for a game that I enjoy, I’ll buy it instead of a new game every time. It’s a blasphemous offshoot of the Cult of the New: I want to see what’s new and exciting in the euro field, but I prefer to do it from the comfort of my familiar, well-loved games.
And when this works, it really works. I’ve recorded exactly two games with more than 100 plays: Pathfinder Adventure Card Game (2013) and Dominion (2008). Both are picture-perfect expandable games that have huge variability without changing the complexity or core values of the game.
Conversely, I’ve recently realized that I also poison my games with expansions. I have multiple well-loved games on my shelves that I’ve stopped playing because the last expansion I put into the box made the game either less fun to play or more complex to teach. Race for the Galaxy (2007) suffered from expansion #3, The Brink of War (2010), which introduced a “prestige” mechanism that was just one complexity too many. It’s only been brought out one or two times since that expansion went in. 7 Wonders (2010) might have suffered the same fate after expansion #2, Cities (2012). went into the box, as it added punitive take-that mechanics that made the game not-fun for players who ended up on the short side of the taxation stick, but fortunately I had the presence of mind to toss that bad expansion out. Carcassonne (2000) recently didn’t go on a family trip, because I thought that the inclusion of the first two expansions made it too difficult to teach to newcomers, even if I do think that’s the perfect balance for thoughtful play. Eminent Domain (2011), complete with Escalation (2014) and Exotica (2016), almost suffered the same fate due to my own intimidation at the multiple rule sets, but I eventually pushed through to relearn how variable ships and mining worked and was able to successfully bring it to the table, but it was a near thing and the huge piles of technology cards still caused problems.
In other words, though I uncritically purchase new expansions for my best-loved games, I think it actually would serve us all to be critical about what expansions we buy, because some can increase our enjoyment of those games, while others can be silent killers that consign their games to never leave their game-shelf homes behind.
