I mean to say that I see the value in determining certain things by chance, yes. You can also have strict rules, just so long as participation in an RP doesn't feel like a game. I'll admit it's a little amusing when the barbarian fails his STR check and bounces off a door, while the halfling bard is able to blow it off it's hinges with his shoulder. It's funny at a table surrounded by players to laugh at the dice rolls. Though most players on a forum will not be happy to have wasted a week narrating the barbarian trying to blow down a door. 

Chance mechanics work better as a way to make events more unpredictable. I recently had a spin-the-bottle game going between a bunch of players, and I left my rolls entirely to chance. The interactions that the bottle game created were not ones that I would normally have thought of, but that was part of what made them so entertaining. Though as is always with chance, it can be kind of weird sometimes. That bottle really favored certain characters, and all of my characters got paired up with the same person.
