I saw the difficulty levels from Divinity in another post and I saw one on of them was things like increasing player health and damage.
Instead of that, I'd like rather like differences to character creation, especially towards common char gen house rules.
Increased points for Ability Scores. (30 or 32) Free bonus Feat at 1st Level.
Stuff like that.
But I also much prefer XCOM's way of doing difficulty where it has the four levels, yeah, but it also has a large list of options to click or unclick so that the difficulty settings of a particular campaign are personalized.
So things like:
Minion hordes (1 HP monsters) on/off Jump Bonus/Action Shove Bonus/Action Shove base distance 5ft/Str based Interactive Environment features (exploding barrels etc) frequency slider Enemy shove on/off Enemy jump on/off Enemy seek backstab on/off Height Advantage on/off Treasure value slider
