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

This tech demo 100% did, that was not a lie. But its important to remember this was a tech demo, not the full game which is still being worked on.

We are just as excited as everyone else to dig into the full game once it launches!

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 :)

Hey,
We have so many bugs fixed in 5.6, so probably the best thing you can do is test your issues there (by compiling source from Github) and report to us if still broken.

You can also engage with the community on the #ai channel on the Unreal Source Discord. I try to frequent discussions there.

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

Europe: Hold my beer. Typical to have tax rates here over 40% :) but then again we have those terrible things like social health insurance :D
