From what I have seen, it appears that the actors in this game change accent depending on their race in the game, acheiving the same effect using different British accents. And as I said last time, how does barely clothed dudes fit Americans more than British people? It seems like a fairly neutral point to me, so either would be acceptable.
Also, a lot of LotR's cast were American and Australian, and they tended to all speak in RP, a British but deliberately neutral accent. There are some variations, such as the orcs speaking like dockworkers, but that's getting off the point-the actors weren't all British and most used a neutral-sounding accent.
But that's enough about accents, I think. We can at least agree that it isn't going anywhere. I just don't think that sci-fi settings favour either British or American accents. It's a bit different for fantasy since most fantasy settings are Britain analogues, but for those that aren't...
I also agree about the clips being awesome. I highly recommend everybody check out the 6 videos available on the official website.
