Even though its not a genre I usually enjoy, I decided to give Clair Obscur: Expedition 33 a go, and I'm glad I did!
One of the most unique games I've played, probably one of my top 10 favorites.
This is going to win all the awards this year :) #GOTY

Its been a while since a game 100% hooked me from the start, but Kingdom Come Deliverance 2 has definitely done so! World building, story, characters and systems are all amazing here and I look forward to really dive in for the next 100? hours or so :)

I just started playing Assassins Creed: Shadows, and really enjoying it! Weird how that "internet rage" often feels disconnected from reality.

Its been a difficult game to get into, but I'm really enjoying Warframe these days! Good alternative to Destiny 2, which sadly is a shadow of what that game used to be :/

Sometimes I feel like my views are radical... Its simple, be kind and treat everyone equally. But I must admit my tolerance for hate is low.

Those of you still using Behavior Trees in Unreal, are there reasons why you havent switched over to using State Tree? Im genuinely interested to hear, and what we can do to improve the tool.

My reaction when a new NVidia GPU is announced: "Wow those are some huge gains!"
My reaction when a new CPU is announced: "Meh"
Why is the CPU industry not on the same incremental growth curve? Is it a lack of a driver/need?
