I didn't have much experience with the browser-based version, so I read up on Karen's MMO Family article, made an account, and logged in. I was impressed by the game's visuals even though they are fairly primitive, as they do a good job of giving a sense of scale and accurately recreate many of the movie's characters. The game is very active, even during odd times of the day, and the chat is filled with players discussing the finer points of being a viking.
Unfortunately, the game lacks in polish. Is it be good enough to satisfy younger, less picky fans? Possibly, but after playing the browser-based version, I hoped that the mobile version would somehow feel smoother and more natural.
