[Bozos of Bones]

I prefer 3rd edition, because it has a whole lot more sense and logic in it. As Kakero said, the THAC0 and negative AC things are really harder to calculate for PnP than BAB and AC. I wouldn't really say it allows for more power, I'd say it's much more balanced, because a Cleric20/Mage20 is not a level 30 character, as that makes no sense at all, the special effect spells are better, and IMHO the whole thing is just simply evolved. What really got me dumbfounded is that in 2nd ed the Ability system was really confusing, like calculating STR bonuses and AC from DEX by class...
