Author here - I'm planning to create game versions of this benchmark, as well as my other multi-agent benchmarks (https://github.com/lechmazur/step_game, https://github.com/lechmazur/pgg_bench/, and a few others I'm developing). But I'm not sure if a leaderboard alone would be enough for comparing LLMs to top humans, since it would require playing so many games that it would be tedious. So I think it would be just for fun.
