* decide to either,
A: connect the games to pull their design docs from the database (this requires changing our build architecture so we can run in a browser which we don't know how long this will take, best case is 1 week, worst case is more before we can use the new imported participants in the play game dialog), or

B: display results which are already collected from the game play (this might take 1 week so something at least shows when you login to your phophlo, but will need to be modified after we do A)
