@RogerBW@Da_Gut re "everything interesting about your character you have to invent yourself"
that seems solvable by having rules that help make an interesting character and help you character to change or grow over time. That is to say, grow as a character not "become more powerful". Because "I'm powerful" gets old fast, unless you're really into bullying people.
And i'd MUCH rather play a game that was like "hey, lemme help you create and grow an awesome character" than MOAR POWER!!!!
