You are correct, swastikas (and other symbols of the national socialists) had to be replaced/removed in Germany in the past. Nowadays games have been recognized as art form and a game developer can request admission to the German market without removing the symbols first. I'm not sure if there's already a game which did this on the market.

First game that was allowed to do so was “Through the Darkest of Times”[1] by Paintbucket Games. I’m not sure Wolfenstein or l4d would get a clearance though.

L4D has no swastikas, so no problem there :) Wolfenstein yeah.. that's a different story xD

Would be an interesting case. After all, 'Inglourious Basterds' was allowed to show them and it seems hard to argue how that movie is different from a Wolfenstein game.

Recent Wolfenstein games are all about a timeline in which the Nazis won WW2 using advanced technology looted from an ancient superadvanced civilization.

So I could see "an entire world where the Nazis won WW2, and the resulting propaganda everywhere" getting a hard look.
