I dont play games on my phone much, unless its very basic like Dots and 3D games are just not for me anymore. Yes I do take a lot of photos but I have learned to clear it off quickly because I hate wasting space - same @ my office, hate clutterness, either upload to facebook/instagram and then delete. My full music library stays on my mac itunes and ipod only the favs go to my phone. I was just looking at my 16gb iPhone 5 storage, till 7gb to go :S....So same as you OP i am going with Space Grey 16GB iPhone 6 Plus
