Here is a subset of rules that haven't been discussed, starting with the mindset-changing campaign philosophy for the first bunch.
Philosophy
In the modern world, experience counts for a good deal. But once you hit a certain point, you are pretty much locked in place as an individual. Some people takes years of life experience to get there. Others are just naturally gifted at most everything they do, and even as rookies have the ability to match veterans in most respects.
In short, the competence of people, and their heroic quality, is 95% innate once they become adults.
It is unlikely that you will level more than three or four times in the life-time of your character after they are made, unless I am purposefully running a game for junior characters.
House Rules
* I use retroactive skill point gain for Intelligence increase. These skill points must be spent through a process of formal training. You do not suffer skill loss retroactively, but you might no longer understand how your skills work.
* At every age category, you may shift up to your Intelligence bonus times your Character Level in skills between all skills in which you have at least one rank. This represents changing priorities or interests as your life progresses.
* Action points will be handed out for heroism and thorough success in challenges that did not depend on Action Points for victory.
* Every three months (quarterly period), that a character spends predominantly on his 'day-job' will be treated as leveling for purposes of finances. That is, new Profession checks and all that.

Favor: This talent represents the possession of a wider contact network. Your favor bonus may freely be used as a bonus to Gather Information checks. This is in addition to any circumstance bonuses for taking advantage of your character's background, dayjob, or named associates.
Finesse Style: At Character Creation, anyone may choose to use Finesse Style. This means that with Finesseable weapons, they always use Dexterity instead of Strength for the Attack Bonus. You suffer a non-proficiency penalty for trying to use the other ability score with a weapon.
The Weapon Finesse feat (now called Weapon Style) makes you in a sense 'ambidextrous', letting you use Dexterity or Strength, whichever is more convenient. This does not allow you to use Dextery properly with non-finesseable weapons, such an attempt results in a -4 nonproficiency penalty.
Take Aim: As per Dead Aim, but only within 30'. Scopes and other targeting aids expand this range. With the Dead Aim feat you may Take Aim to any visible range, and the bonuses to hit becomes +3.
