Wolfenstein TNO is great, Wolfenstein II is half great.
It's two games in one. After a great intro it starts out as a bizarre political commentary and you will find some of the weirdest shit you've ever in games.
At some point a Ginger Scotsman is called out as a WHITE FASCIST PIG by another polygon form. It was quite something.
Halfway through it seems like someone said: "Enough of this shit, let's kill some Nazi's" and it actually turns good.
However they cut a whole bunch of gameplay mechanics and simplified some things.
It has some moments that are better than the first game but overall the first game was a more complete and balanced package.
