I came to the same conclusion for adding usage logging and promo codes to my app. Use Parse for now but try not to use too much of their API and to keep it to a couple of particular lasses that I access it through so that if I need to move it is just a day changing the app and one or two setting up and securing a server with a database. Not a game but a lists app focussed on reusable lists for things like shopping and packing with a couple of neat features. Http://iTunes.com/apps/fastlists. Free with in-apps if you like it. I haven't decided how to do shared lists yet, iCloud, Parse, custom server or something else.
