I think in this case, given the structure around the rules, I could imagine the mean “partisan” in a more explicit sense: A game where you play as the Democrats to defeat Republicans would be explicitly partisan. A game where you learn about the consequences of defunding social security, in a way that nudges you away from cutting social security probably wouldn’t be considered partisan, even though it’s an issue ghat largely follows party lines. That’s just my speculation, though
