Supplementation and house rules focused on how to “make the players a little more powerful earlier” also tend to introduce bad and arbitrary mechanics too. Guard against changes that raise the complexity or split from the symmetric balance.
If you deviate from the standard norm, consider the effect the deviation will have.
- Will every player want to have the “insert here” rule in their favor? W
- ill having it put the other players at a serious disadvantage?
- Or, worse, will the players having such a change in the rule set in their favor cause you, as the GM, to escalate the conflicts they face?
- Raise the difficulties and threats to the point of the extreme in order to handle it?
