I've been enjoying EndeavourOS over the past three years. It works wonderfully out of the box at default settings, and was really easy for me to use and set up to my liking with minimal know-how needed.
It also works really well on the variety of machines I have in my home. My desktop, modded Chromebook, and my husband's laptop.
It's allowed me to get more familiar and confident with the command line, and enough so that I've switched to Sway from XFCE (and previously KDE).
Probably the Hardsuit Labs version of Bloodlines 2. Playing as a thin-blood and getting to diablerie would have been really fun.
I spent the whole game as Evie unless forced to play as Jacob. And other than those inane carriage sections I found it very enjoyable.
I haven't played Unity, but I've watched it being played and definitely hard agree on the difference between the parkour. At least in Syndicate, Evie feels more fluid compared to her brother.
The WW1 section was my favourite, honestly, even though it was so short.
Big agree about Warframe. I've been playing since 2017 and have not once joined a lobby. The game is very playable solo.
