The choices you made before deciding your character name
The first question determines your starting headgear… and i think the rest just tailor your personal story a bit but not by much.
Some of the choices will result in going on a personal story path instead of another. On that particular character you will lose the ability to see the other story paths, but with an alternate character or grouping with a friend doing his/her personal story, you can eventually see all the paths. Bear in mind that even after you finish creating your character you will have to make decisions from time to time on which way to proceed. On everything, really just pick whatever suits you, whatever you seem to like most.
PS: About the headgear. If you like the one you chose, do not throw it away after you find one with better stats. I think you can transmute it’s skin. Many people ask on the forums how can they get back their starting helms they threw away.
They effect starting gear ,personal story lines and your starting personality .
A side note on gear . The Engineer is the only profession that can start with a back piece . This in my opinion makes it the best choice as it counts as a piece of armor and you wont get another till late in your personal story .
Every race and profession combo has 4 questions. One is the same for everyone (where you can pick your personality, like dignity or ferocity). This is important cause it sets the mood for how npc’s react to you. However, your actions later in game can change this and it is a minor thing (I never paid attention to what way I am and I don’t see a big difference in the reactions).
There is also a question bout a certain part of gear. Again this is personal and adds one starting gear. the other gear slots can be filled pretty soon (with the exception of the engineer, if you didn’t pick backpack, you need to play a long time till you get another back-item)
The last two questions depend on your race and set the tone for your first parts of your personal story. (untill level 20)
For example my human engineer decided that I grew up as a noble and I always wanted to join the circus. The first part (till level 10 or so) of the personal story you spent with your noble friends, the second part (lvl 10-ish till 20) means you are tasked with infiltrating the circus. However, if you decided to be raised on the street you need to help your gang friends in the fight against another gang.
If instead of being in the circus, you decided that you greatest regret is that you never looked for your death sister, you are suddenly taksed to do that at level 10.
So this only changes thing for lvl 1-20, after that the storyline branches into the direction of picking an order and is the same for everyone of your race (though you are offered new choiches then).
Arise, opressed of Tyria!
