I was also hesitating whether to buy No Man's Sky or not, but after reading mixed reviews decided not to. I have my money saved in advance for only 1 game this fall... Battlefield 1. I think it is going to be amazing. We haven't got a decent WW1 shooter in ages.
I love to play online shooters and mostly turn on my PS4 to play SW: Battlefront and Battlefield 4. I usually buy 1 game every 6 months and they are mostly multiplayer-based so I can get more value for my money. Single-player is done after you complete the campaign, but multiplayer you can play every now and then and it always feels fresh.
