I got down to 5.5 GB on the hard drive of my Macbook Pro. I ran a sweeper program on it and found that the Mobile Applications folder has a size of 69 GB's. I have not played most of the iPhone/iPad games in over a year. Would it be safe to delete the files? I don't really care that I'm risking that some of them are no longer on sale in the App store. If I haven't used them in a year, then it's no big deal to me to potentially lose access to some of them.
