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 :)

Finally upgraded my keyboard, got one of those fancy Keychron Q6 Max now.. damn the thing is smooth and responsive! Been using a WASD Code for the last 11 or so years.

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

Im very excited about the work my team has been doing for Unreal 5.6, its turning out to be a big release for us.

Huge improvements to State Tree and Mass, among others :) Cant wait to see what you all think!

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.

Anyone else feel like sometime their productivity gets supercharged simply by finding the right music to your current mood?

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?

Back to work tomorrow, huge stack of exciting projects awaits!

Happy new year from Berlin! Streets here were an absolute warzone at midnight.
