The probability is a bit more complicated than for straight rolling 3d6 (or even 4d6-drop-the-lowest) so I haven’t figured it out. But you are guaranteed to get more 6s than the statistical average (5 out of 18 rather than 3 out of 18 or 4 out of 24-drop-the-lowest-6), so it's just a question of whether you'll get them lumped together or not.

Its really not more complicated than rolling. The probability of drawing an eighteen in this method is 1.225% (approx). compared to 0.463% (approx) on 3d6. so its a tad under three times as likely. Rolling an 18 on 4d6 drop the lowest is 1.620% (approx) so its the most likely.

or for those who prefer fractions to decimals thats - 5 in 408 (just a smidge worse than benj's guess of 1/81(5/405)), 1 in 216 and 7 in 432.
simple.
(okay I needed piece of paper for the 4d6 one)

That seems more worthwhile than the usual methods. When running DnD, I don't really care about PC stats anyway, as everybody whines if things aren't roughly equal (and powerful)
