Huh? Differing expectations is not simply a matter of "should we play defense or offense" in a team game, it's a disconnect on what the goals for game itself actually are & even what rules to follow. It is simply not possible to throw everything on the gm to simply "mix and match stuff" when a player has different expectations of the game. There is no way to include a catchers mitt in golf or bowling and an ambulance needs to be on the scene real fast if a baseball bat is ever used in a game of hockey or football. If one player has a different set of "expectations" than the GM & the other players at the table it's somehow the job of everyone else to accommodate ThatGuy's desire to play baseball even though everyone else is playing a game other than baseball rather than having ThatGuy adjust his expectations?I disagree. You can mix and match stuff, do things that various players care about, pretty freely. If there's a legit difference in agenda that cannot be accommodated, then sure, we have a issue that isn't going to resolve. But, here's the thing, the GM can be that player that has the difference of agenda and "Trust the GM" provides cover for that so that it doesn't come up. Maybe I, as a player, speak up about a mismatch, and everyone at the table would agree with me, but immediately get to see me get shut down by the GM for being wrong, so they start to think maybe they're wrong, and then I leave the table and the GM says "good riddance." So, since I as another player might prefer that what the leaving player wanted but can deal with what the GM is handing out as acceptable, I don't open my mouth because I'm not suppose to question the GM.
Instead of "Trust the GM" why isn't the predominate culture "engage honestly and openly and have difficult discussions with respect for all and a healthy dose of self reflection?" That's out there, and we're seeing more of it, but there's the old guard "Trust the GM and Never Trust Players" that's still here and fighting.
No matter how (un)common problem players & players with different expectations are in the wild, the number is never going to be zero. The GM is afforded trust & authority to keep things running at the table when that number is one or more at the table. Your posts read like the number is always going to be zero or it's the GM's fault for poor communication.
