3 points every time you create a storygame seems inoffensive right? Well, if you don't care about users getting points for free then it's fine, it's not like you have any reason to enforce the point system.
In the other hand, any user is able to get over 9 points per minute of more just by creating and deleting storygames without publishing them. So, if you could remove that feature it would be fine for me and that crazy bearded man behind you :)
P.S: Could you make a "preview" button before posting here? I miss that feature from other forums ^^
