I couldn't decide what class to play so I rolled a Sorc, Merc and Op and played all three to level 30 before deciding. That means I played the first 30 levels on three characters with a fairly small amount of time between them.
What I can say is this:
- The (non-class) quests for all three characters were virtually identical. Only the conversations were slightly different here and there ("My Lord" instead of "Sir" etc.)
- If there are any differences what so ever then they are so small that it doesn't make re-playing the game any less boring then re-rolling in any other MMO.
- The class quests are virtually identical just with a slightly different story-background. Each of my characters had to travel to planet X and infiltrate base Y to perform mission Z.
- All characters had to visit every single planet. There is no variation what so ever. If you've been to Tatooine once then you've been there a hundred times - nothing changes what so ever.
So after noticing this I thought "well, that's disappointing, guess the only reason to re-play the quests is so I can make different choices when it comes to karma - perhaps this will change the following quests". Sadly it turned out that all these "decisions" are totally irrelevant in every way. None of your actions have ANY consequences what so ever. So if I choose to betray my quest giver on my first character then I did not betray him on my second play-through. Sadly this made NO difference at all. Two lines of voice acting are slightly different but that's it. The following quests are not changed in any way, shape or form.
Any kind of "story diversity" (being good, being evil, selecting to betray this person or not) have no influence what so ever.
This is not only true for non-class quests. Even the "key" events in your class quest have absolutely NO influence on the rest of the quest. You can be a total bastard and betray everyone or be the kindest person ever - the next quest will be exactly the same.
So basically the only change between play-throughs are very very minor and in no way motivate you to continue listening to all the voice acting. You end up simply space-barring because it gets so *********** boring after the second play-through.
For a "story based MMO" that's supposedly oh so innovative this is a huge HUGE let-down.
The WOW storyline has 10 times more diversity because you can choose which regions to quest in and are not forced to head from one planet to the next without variation. Sure, there's no voice acting but what's the point if it's so *********** boring after a single play-through?
I'd give this game a replay-value of 1 out of 10.
Anyone who claims that the story is so diverse is either lying to you (BW employee in disguise) or never re-rolled a character before (or simply can't remember their previous play-through).
Really, really low BW.
