The point table would need to get further curved to balance the probabilities:   (3=0 pt, 4=x, 5=.5 pt, 6=1 pt, 7=1.5 pt, 8=2 pt, 9=3 pt, 10=4 pt, 11=5 pt, 12=6pt, 13=8pt, 14=10 pt, 15=13 pt)Then roll "4d6 keep 3" (in-order, no cheating) and keep either the roll or the point-buy score.This should give reasonable average scores according to my simulation:[11 11 11 11 11 11] gives an average stat value of 12.9 (avg. char, no bad stats and a random chance of something good)[15 15 10 3 3 3] give an avg stat value of 13.3 (2 very good stats, 13% of improving each very good stat and chance of really bad stat)So we can keep the averages close to normal. Chance of 16/17/18 are same as regular 4d6 keep 3 (but on only have one chance, since it is in-order rolling). Can guarantee 2 good stats for particular character concept. Randomness may bring interesting 'character' to the character -- especially since you can't re-order the stats.  Using 3d6 instead of 4d6 keep 3 drops the averages scores by about 1 (12-12.2) - so you would want to boost the buy points to bring the averages back to the 13 range.</blockquote>
