Some of the accents of the in-game characters can be a little cartoonish at times. I haven't checked the background of some of the voice actors, but I suspect some are non-native speakers trying to do a UK regional accent.

But the accent of some of the Gondorians in Morder has me wonder if they aren't veering off the mark a bit too much. The inflections are quite noticeable and they remind me a lot of the way they have reconstructed the Original pronunciation from Shakespeare's day.

So maybe they saw this video and thought "Oh, this would make a great Gondor accent !" While it ends up making you sound like somebody trying to hard to come up with something that sounds utterly artificial and affected.
