I hate rolling for stats. In a pen-and-paper campaign, it's just a bad way to do things. One person's character is gonna be much better than someone else's just because of stupid luck at character creation. In a video game, everyone's just gonna re-roll until they get a bunch of good rolls, so all that means is that every PC is always overpowered with ridiculous stats. Rolled stats are basically just cheating, to me. Point buy is fair, flexible, and puts every character on the same level.
