Not gonna lie, I get into games very superficially. As someone pointed out on here very recently, across a PS3 with 50+ games, a vita with at least 30 and a PS4 with at least 195, I haven't got one platinum trophy.
My completion rate for games is very low, this year I've actually only "beat" Nier Automata, Shadow of War and Uncharted Lost legacy. Oh and all the fighter story modes, but that barely counts.
But I'm ok with that. I don't pay retail for any of my games really and I do play everything I buy till I get bored. Some games I own will never be completed, but I might fire it up for the odd level every so often.
At the start of this generation I pretty much knew that I won't be going any further. I have always loved gaming but I'm at a age where my other hobbies are far more important and while I might talk about games alot, I don't feel need to play them as much. My PS4 library in particular is not just a library for the generation, it's pretty much my gaming library for life.
