I think it's a pretty cool approach to building the destiny world. One plus, is that new players who pickup the destiny game wouldn't need to purchase the new content until they reach that part of the story unless they wanted it ready or something. So that in itself is really cool. Sometimes game developers understand a lot of new players join in their sequels without ever playing the part 1 of the games legacy. This pretty much takes care of that. New players wouldn't buy destiny and the new content and magically be ported to that campaign point of the game. However, they would have access to that planet though. If the game is not linear at all, it is quite possible the new players can port themselves directly to the new areas and start the campaign differently. Though I find that unlikely. This game is all about telling a story and living it, not getting cliff notes to skip to a certain chapter. There will probably be a main plot, and many sub plots within the story to take away the feeling of the game being considered a pipeline type of story play. This way the games got it's own massive irrigation system in the works, everything connected in a seamless flow. So you can be on a early chapter of the campaign mode, yet travel to a distant planet where the main campaign would normally take you towards the end, and instead of play the main plot perhaps be apart of a sub plot that still has references affiliated with the main plot. side missions, and main missions to progress story line. Some side missions will probably be affected by the story timeline. Meaning that different missions will probably be available or become unavailable depending on where you are at in the game if any of those missions involve main characters or alliances dependent to the mission. So I think it's a cool idea, and wouldn't have any negative affect on old vs new players.
