It depends on what you mean by the "mini game".
If you mean assigning points to build a starting character and, mechanically, best reflect its background, training, interests, etc., then yes.
If you mean players either a) planning out their character character for multiple levels and expecing to be able to follow their build without regard of the setting and in game results; or b) min/maxing/ CharOPs, by powergamers interested in stacking bonuses and/or finding broken combos or , my answer is no.
