I've played The Evil Within + the DLCs and Wolfenstein: The New Order and The Old Blood. I like both of the series but I can only pick up one of the new games.
A bit on my opinions about the games:
TEW I mainly like for the gameplay so, though they did a much better job with the storytelling in The Assignment and The Consequence, I was kind of let down by the well received DLCs because they essentially avoided the combat. Still, they had some good tension like some parts of the main game and overall, I enjoyed them. TEW proper though, is what I remember more. I like the hodge podge horror ride 'cause I don't know that much about the genre but again, the gameplay is what I like the most about TEW. I like fucking with the enemies, making my resources count, and getting familiar with all the weapons. Generally quite satisfying.
Wolfenstein: TNO is a spectacular game. I enjoy the shooting, I didn't have problems with the difficulty (I heard ppl complain about how hard W2 is, is it much more punishing than W1?) but what I was most impressed with were the character work, the writing, and the beautifully directed cinematic moments. The Old Blood however, left a bad taste in my mouth. It's not that it was terrible but when you follow something as special as TNO with something as excruciatingly average as TOB, it's plainly obvious. TOB gave me little tastes of what TNO provided along the way when it should've served me a small portion of it.
I'm a piece of shit and bought both. $25 each, physical won't really get much cheaper than that so decided not to wait. Thanks all for the input. If Wolf 2 is anything like the combat in Wolf 1, it took me a bit but I kinda figured out how they want me to play and I enjoy it so I'm not too worried.
I went full black out on coverage of the games so I think I'm gonna see a lot of good shit.
