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.
