IMO you should give the choice, they might be some new RPG players who are not used to think about their avatar in the first place, (how it should look like in few level, the skillpoints etc...) and some other who do not want to inherit some skill points in useless field just because they gave the wrong answer to a question. The choice also gives you a possibility to play the game in a more RP immersion or just replay it with an optimised avatar (meaning in a more "functionnal" way). I personally like those "personality tests" sometimes you end up with an unexpected avatar. And anyway, whatever influence this has in the first place on your avatar, you will evolve during the game !!
