Knowing the backstory will certainly help, but if you read the wiki first, then enjoy Dark Dawn so much you decide to play the originals afterwards, you'd get spoiled. It's up to you, but I can guess Camelot has made Dark Dawn accessible to Golden Sun newbies, so you might not need to do anything to fully enjoy the game.mjc said:Do you think I should take time out to play the first two GS games or should I just read wiki for the story? I've got a lot of games on my plate at the moment.
You may also want to check out Golden Sun The Abridged Series (warning: spoilers!); it barely covers the first game, but it's very well done (especially from episode 3 onwards).
