I was wondering if anyone has made any house rules about not allowing certain skill checks for characters who are not trained in a skill.
I think it would be odd to have a character who is a savage from a pre-hyperdrive planet jump into a spaceship and be a fairly good pilot because they have a high agility.
In the movies I know that Han Solo was pretty sure that Luke could not fly off planet without him, and that his experience dusting crops would not help him plot a hyperdrive course.
Would it be reasonable to say certain checks could only be done with training?
I was thinking of making the following be attempted only by someone with at least one point in training:
Piloting
Astrogation
Some computer checks (like slicing)
Some medical checks (like surgeries or critical injury healing)
Skulduggery
