Back when I bought this laptop several years ago, I recall the consensus was the 4GB is (barely) enough for new games, and 8GB is when you want to be on the safe side. But back then 32bit games were the norm, it might be now games are being more and more 64bit and maybe demand more RAM?
Cities: Skylines and Train Fever are rather RAM-hungry too (up to 12 GBs used when running those games) when cities and networks become larger. And that's when playing games natively in OS X.
If I want to play games that only run on Windows, I split my RAM between OS X and a VM. I can get away with playing Saints Row 2 with little in the way of hiccups, but Saints Row: The Third and Hard Reset: Redux require more allocation to the VM.
So yes, 16 GBs of RAM is the new 8 GBs for most gamers, but for my usage patterns I'm purchasing a 32 GB RAM kit next week. I tend to play a lot of intensive games as well as multitask, and with OS X being more RAM- and CPU- intensive it leaves little room for Windows unless I upgrade, so your mileage may vary.
