Localizations (the best and worst)

[Deathbringer]

Some American games were censored for reasons that didn't make sense. Like changing the blood in DooM 64 and Hexen 64 from red to green.
From what I've read, this was done on the Japanese versions. I don't see the point when they do have games with red blood in them.
With both games, you're pretty much fighting monsters. And Japan has heaps of violent & gory anime and manga as well.

But take a look at the South Korean version of Duke Nukem 3D. The enemies bleed white, which looks so wrong!

And yet strangely appropriate.
