I just got my 2nd talent increase (both in Power), after only 3-1/2 years (age 22). If my talent ratings keep changing at this rate (1 shift every 1-2 years), I think I'll be quite happy with this aspect of the game. Rare enough that your starting settings will always matter, but frequent enough that you don't feel stagnant once you reach your initial peak.
Now if I could only figure out how to get increases in a few other areas. Anyone got any idea what workout routine will improve my Eye talent?
EDIT> me, my; pronoun, adjective -- it's all the same.
