Is it time to cut the war game roots of role-playing?

I bolded what I feel is important. Having flaws is not an issue if you still try to succeed despite them.

Quote from Reiner Knizia about boardgames that I think can apply to RPGs as well:
'When playing a game, the goal is to win, but it is the goal that is important, not the winning'

meaning that as long as everyone tries to win, the game works and is fun to play, even if you lose. It's no fun winning or even playing a board game if your opponents actively tries to lose or simply don't care.

In an RPG, having your character actively trying to lose is not fun (to me). However, eventually losing can be fun as long as you have tried your best to avoid it!

The problem with doing this most RPGS is that they dont have any (or atleast any good) mechanics for modelling personality flaws, and thus it is up to the player to set their own limits.

It is much easier in single author fiction where you can play up the character's struggles and weaknesses but still have them succeed (or lose) through author FIAT.
