hmmm... if you can become highly skilled @ everything, then you will probably work with something like lvl\'s and experience, and for every lvl you want to increase, you will need more exp, like 1000 for lvl 1, 2000 for lvl 2 etc. and i dont mean, 1000 = lvl 1 2000= lvl2, more like 1000=lvl 1, 3000=lvl 2.
