I feel slightly sorry for Ready at Dawn. Their game is having a rough time in the reviews.
I agree with the OP, they made the game they wanted to make but maybe that is not the game most people want to play - it is no COD or BF game for sure.
For me, I like the game so far. Probably partly because it was a very long time since I played a shooter and I enjoy games having atmosphere, interesting characters and story.
I also like AAA games that actually work day one unlike so many other games lately.
