As the person who said they noticed an increase in quality players in an open sheet system, I am talking about the perception that someone could fact check you significantly cutting down on the following behaviors:
*weird ooc lying about stats, whether that's the guy in the ooc room telling everyone hes a badass, to people who RP and brag oocly about their PC having the social and diplomatic skills of Madame de Pompadour but are actually more on the level of Elliot Rodger when it comes to how they've invested in their PC.
*People constantly convinced (with the whining and/or overcompensating that follows) about how they are The Most Underpowered PC On The Game So They Cant Do Anything With Anyone But Mope. Yes, there will always be people who freak the fuck out when they cant throw 4 million dice at something like they're use to on their last high powered WoD game; but when people can see that oh wow everyone's in the same boat, and see for themselves (or know that they could if they wanted to) what the spread of differing "levels" of old and new PC are...they seem to relax more quickly. Also, honestly? As someone who is real mechanics challenged, it's been kind of nice in the past to have gotten asked after a scene "hey, I noticed you were frustrated about not getting x to work, would you like some mechanics advice? I see some ways that would be an easy way to improve that."
*ST for a PrP being surprised with a shitload of power inappropriate to the scene they're running and having to deal with that after the action has started. Of course this requires that they care/are attentive in the first place, open sheets dont magically fix that.
*the perpetual problem of people getting offended you dont know public stuff about them, but they havent updated their +finger/info or wiki since chargen.
I find that transparency tends to set up a more collaborative environment. You can have that with secret sheets and no wiki/finger info in a hard PvP environment, though, I've seen it happen.
And I dont think sheet transparency is a great thing in non-consent games where staff is inattentive/unavailable, and where there is no sense of community.
Maybe that is why on the whole I have found a better caliber of ooc player behaviors on games with open sheets, they have all tended to be smaller with a better sense of ooc community.
I am a grumpy ass old lady now, quite literally. If I log on to a game, I like it to be a polite, collegial ooc environment, and there to be a minimum of impediments to being able to get playing with others and getting my ic risk taking on. Things that spread the ST load/ability to people beyond the (usually understaffed/overworked/stressed out) staffers on a game seem to help it stay afloat longer.
