Why can't you ignore them? The Catholic church also has a very high number of users and you surely ignore those wrt competing with Steam. The Vatican is certainly in an even worse position to convert users to game shoppers, but I don't think that Facebook is that far ahead in this. People have pretty much stabilised in how they expect their relationship with Facebook to be and any offers to extend it to new grounds are likely to be ignored. When Farmville happened, Facebook users were a lot more experimental.
