Facebook game lack creativity

I never play facebook game now, i think most facebook games is a copied of other apps before. I feel the same element every time i play facebook game. It mostly give us energy / stamina / health that heal over time. It usually require us to refer a lot of friend to become strong / rich. And what i don't like most, it usually require us to get back to the apps in a certain time ( to collect money / crops / etc ). What do you think about this? Do you agree with me? Or do you have different view? Please share it with us.
