I get game requests every single day... And not just Candy Crush requests. Slot machine games my aunt plays, my dad and a couple relatives play Candy Crush, and a few play Farmville. I honestly get more game notifications than any other notification on Facebook.
I also hate pay to play apps, but I hate apps that are free with in game purchases even more. In a lot of games there's always that second currency that you need, but it requires real money to get said currency. The only other way is to do those "Install this game and get (however much) of this (currency or item!)" offers. Those take forever and they give barely any reward. I refuse to buy any in game purchases on my phone, so unless it's a game I really like and I am willing to do the offers for the items, I will just unstall the app and look for another.
