Basically, if you want to play an CRPG like PnP game you would need a team of developers just sitting there, waiting to redo the game so you can do whatever you want.
*You see the house of the evil wizard you've been looking for. You try the door, it's locked.*
"Crap, I don't have lockpick on me and I'm not strong enough to bust it down."
*You look down and see two rocks and some dry branches*
"Hey, developers!"
"Yes sir?"
"Can you make it so I can bang these rocks together, making a spark, igniting these branches, then using the branches to burn the house down?"
"Sure!"
