Yep, starting at first level.
Max HP/level (but this doesn't matter right now since we're starting at lvl 1 anyway)
Ability scores: 4d6 drop low, 7 times (dropping lowest score, roll using the board roller) OR 32 point buy (d&d style)
Classes: 3.5 or PF versions, your choice.
If you choose the PF version of a class, you get the PF version of spells too - no 3.5 Polymorph if you chose a PF Sorcerer, and no Create Pit on a 3.5 Wizard.
Skills: 3.5 versions. If you have the PF version of a class, you get all the corresponding 3.5 skills as class skills, and an extra skill point per level per skill that had to be split up to compensate.
Feats: Pick whichever version you like better. Up to 2 3.5 flaws, and up to 2 PF Traits (one of which must be a
Kingmaker Campaign Trait). We'll be using the PF feat progression (one every odd level) instead of the 3.5 one. So lots of feats.
Races: PF version, unless you really like the 3.5 version for some reason.
Optimization Level: Don't go too crazy. This is an AP after all, so it's pretty easy. I'd prefer not to have to alter it too much. I'm not gonna hard-ban anything, but... don't be a dick.
