So... Ever since 7.5 Ed came out, I have been wondering about the relative cost of characteristic points in the various editions, since characteristics points are generally more important than levels in T&T. My latest approach was to see how many AP it would take to raise a character with a value of 10 in every characteristic up to 20 in every characteristic.
This is what I got:
5.5: (Assuming WIZ and SPD cost the same to raise as DEX and IQ): 1,000,000 (16th level) M6: 1,105, 000 (66th level) 7.0: 116,000 (2nd level) 7.5: 11,600 (2nd level)
