Concerning mini-games/puzzles that might be a part of D:OS - I think it would be nice if you could say "I let my character do it" if you don't feel inclined to do it yourself. In a game with several different components, the player doesn't have to like all of them, but might still like to finish the game or a particular quest.
For example, there might be a puzzle - the player isn't keen on solving puzzles and doesn't want to bother looking for a solution, but says "Hey, my character has high intelligence, so he should be able to figure it out." You include an option to choose an attribute check instead of solving the puzzle manually.
If a card game is part of D:OS and the player doesn't want to play it, she could say "My character is so dextrous, she tries to win by cheating." Again, an option with an attribute check could be chosen to replace the actual game.
High dexterity could also lead to automatically being successful in a jumping challenge or a race, while high intelligence could replace anything that involves using your brain as a player.
High strength, on the other hand, could be used to instantly win fights if the player doesn't want to actually play them. I know many people consider fights to be integral parts of role-playing games, but some don't. They are more interested in the story and in questing. There are also some people who don't like turn-based combat although they would be generally interested in D:OS. For those, it could be an option to create a very strong character, allowing them to skip all fights.
With such a system, every player could focus on the parts of the game they like best.
