There are a lot of things to like about Wolfenstein, and very little to dislike. The only dislike that I could think of is the basics of the FPS where its not going to be as involved as a Battlefield, but not that basic either.
The likes, the story is great! What's not to like when you're talking about killin' nazis. What they did with the alternate reality and how intense things would've been with Nazis' domination (spoiler) was great (including the different weapons and vehicles).
The missions, the great thing I enjoyed about this as opposed to other FPS was I never got tired of the story missions. They kept going, getting more involved and taking you to further places (it would've been nice to see more of the world under Nazis' rule (US, parts of Africa, China/Japan, etc.). But nonetheless the missions were good.
Lastly, the graphics were nice, not as detailed as a Titanfall, Battlefield, etc. but still very good. Definitely worth the rent, one of those games where you would love to see how they could turn it around into a sequel (maybe the build up of the resistance through another character's POV).
