Just started the new Digimon Story Cyber Sleuth: Hackers Memory. And despite the overly long name, its just as good as the previous one.
These are some of the few games ill buy day one, as a sign of support and because im a huge digimon fan/digimon games have been killing it the last few years.
Also try to start Gravity Rush 2 since it finally hit the sales with a hefty cut in price. Should be playing Xenoblade 2 but I'm having too much fun with my new surround sound kit, friggin love it (when I finally got it working after almost two days of tinkering with it).
Then going to try to play some Halo:MCC, also later in the day Mortal Kombat XL.
