Slingo and other Casuals

• Most casuals use this potential energy type of model in order to limit users / monetize gameplay.
• Some stress energy more than others
• Energy is less important in Slingo than in Sim City Social for example (just a hunch)
• Less important in terms of % of revenue collected by users buying energy

• I would be interested in knowing what the expected loss in daily revenue would be by giving users each say 10 energy for games like Slingo compared with Sim City Social.
• Is there a standard measurement for this idea? 
• I think this is incredibly important to understand in order to provide the right amount of free energy for possibly daily focused advertisements.
• Give users 5 energy for visiting this other site for example, or trying a different game.
• Well great, you got them to use another game. More money right?!
• Maybe not, maybe the cost of dishing out 5 energy just outweighed the profit of the ad.

No one really reads these, yet! :), but if anyone has some insight on this I would love to hear about it. Gotta get back to work!
