I believe it is 16 perks per skill which is (18 * 16 = 288) Hey the more the better right?
Yeah, but the point i was making was hopefully there will be far less Ranked Perks (1/5 sneak damage "you get +10% more sneak attack damage") and more things like Shield Bash, 10x sneak damage with daggers, lightning bouncing around rooms and all those cool things.
also, in the interview he said 220, which is why i said the 12.22 per tree as that would be at the 220 mark. remember, the more perks they have, the harder it is to make unique perks and start adding in ranked ones... which i hate.
