The same page tool is a list of questions with answers which represent different approaches to playing role playing games. For more information, check the related question What's the purpose of the same page tool?.
The starting points of this question would be:
- I have some players who probably would like to play together, but probably won't. I don't know it yet, and they don't really know each other.
- I have GMed for some of them personally, but never for all of them at the same moment.
- Some of them haven't played with me before, but are not totally new to RPGs.
- I don't know exactly what might raise a conflict.
- As a GM, I am ready to accept pretty much any set of answers to SPT questions, but want my group to be on the same page. As one of the answers in the "What's the purpose of the same page tool?" question states, it is mainly intended to be filled in by the GM to codify things. I am not that kind of GM.
So my idea was to use Same Page Tool as a survey, which is contrary to its description. I wanted to understand which of those players might be compatible and which are totally incompatible with each other.
If they are just slightly disagreed, I may ask some of them not to do some things they expect -- most probably, for example, ask one player who wants to have an intra-party conflict to avoid them, or to tell someone who I know is a rules lawyer that I am not going to rely on the rules at all -- they won't even get character sheets, and I don't use dice.
If some of them want totally different games, I would rather play with each of them separately, or make several groups.
So, why is using it as a survey bad?
I want to remind everyone to only answer from your experience. For example, "I have used Same Page Tool as a survey, and here are the problems it caused, which could otherwise be avoided...", "I have used it as a survey, and I didn't get any problems, because...", etc. Not "I didn't use it personally, but probably it may cause this and this and this".
"I have seen it used this way, but not by me" is OK.
