Hickory: I have very strict rules I set for my character creation. I have a set number of rolls I am allowed to make, depending on the game. I cannot 'store'/'recall', and I cannot redistribute points, so I must make the best of what the rolls offer, and if I reject the best of the rolls, then tough. I've never rolled higher than 86, and rarely get more than 80.
Personally, I don't like my stats being governed by chance, and therefore will either:
1. Ctrl-8 cheat to get all 18s in my stats (it isn't quite as much of an advantage as you might think because not everyone has uses for all stats, or
2. Choose some number, Ctrl-8 my stats if needed, then adjust my stats so that they add up to the chosen number.
3. Limit specific stats, but not all.
Note that I so far have been using option 1, and will likely only use 2 or 3 if I've played the game enough so that 1 starts feeling too easy. This might never happen for me with these games because I've found I just don't like the games enough to actually finish them.
