Add this to the game breaking glitches we have been hearing about. :banghead:
It's not a glitch, I assume Obsidian made this change on purpose. In the original Fallout, 1 and 2, you selected a perk every 3 levels. I think it was a necessary change because in F03 at level 30, with the right perks selected, your character was a God even on Very Hard difficulty. To me it balances the game out much better, makes you have to think if I should take perk A over perk B, etc.
