I got to what I assumed to be the last boss after playing through some of the toughest battles in the game for close to an hour, and right as the cutscene ended, it decided to crash. I thought it wouldn't be a big deal since most modern games are busted and crashes are expected, but lo and behold, my save data is gone and I have to start all over again.
Fuck that, and fuck this game. I really loved everything about it up to this point and wanted to keep it in my collection but I just can't let it hurt me again. Goodbye, Wolfenstein, it was fun while it lasted.
