It is challenging no doubt, but it appeals to me because it is so bleak. Misery is a love it or hate it kinda thing.
The last time I played would have been around 2013, and I was playing Misery 2.0. I played the Metro games again, and once done still had my post-apocalyptic groove on, so decided to look into getting Stalker back up and running.
Recently I wanted to get back in to Stalker.
