With the amount of applications on facebook is it still worth it? How badly have facebook updates affected app post in the feeds to generate new users?
I work for FreeOnlineGames.com and one thing i am thinking about for my next project will be a facebook arcade.We already have a large fan base over 600k likes on our page so i could easily promote it with this.But the arcade will take a lot of work, making it in the first place working out how to add games, if we should use all or just high score games, adding achievements and other competitive/ social elements.

Do any of you with experience in facebook aps have any advice to share? Have you noticed any changes in the amount of users lately? Would you recommend it or not?

Thanks all 

First advice – use open graph beta ( https://developers.facebook.com/docs/beta/) !

@leopoldpanovi Excellent! Thank you

@sudeep Sounds good, that is exactly what i am aiming for
