It does appear we forgot a ) in the example. Oh well. some things do occasionally sneak past spellcheckers and grammar control. A result of writing while megatasking, we suppose. 

also [@SleepingSilence]... That example doesn't actually make much of any choices for the other player... all it says is that the player must be willing to play such, not that she would need to actually play that. In fact, the bit "Not that the RP will concern such" specifically implies playing such is not going to be the plot.

But that's a bit of a digression.
