How to replay a game in Facebook?

How can I calculate acquisition cost per user for a Facebook game in 2011 vs a game outside of Facebook?

• When planning a game release which is better: on Facebook or off, and what factors should be used in evaluating that with the changing Facebook rules, Google search and user trends and expectations.

• Answer:

  First, you should be able to easily run tests on Facebook and Google to see what the cost per install is for your target demographic.  Second, do you already have a payments system? Are you OK with using Facebook credits and sharing 30% with Facebook?  If you are comfortable using another system then you can keep more revenue for yourself. Third, and most important, it really depends on your game.  Was it designed to take advantage of the Facebook platform?  Will the casual players on FB enjoy the game or is it more suited to a longer play session,more hardcore player.  This is ultimate question you need to decide, and should take into account throughout the game design process.  It is definitely not a one-size-fits-all market, different games will have varying levels of success depending on the platform.
