One thing I can say I immediately dislike about Wolfenstein 2 is the lack of "Restart from checkpoint" and "Restart level" features. It was a lot of fun to replay sections in TNO and TOB to try and do them multiple ways, either stealthy or guns blazing. I try not to speak about game design decisions in objective or definitive terms like this, but I view the removal of these features for Wolfenstein 2 to be a legitimate step backwards. There's save slots now so I guess I just need to remember to use them instead.
Rest of the game is great so far though.
