I wanted to get the group's opinion on something else skill related as well.
How do you feel about making multiple skill rolls to achieve a single result? The best example I can think of can be found in Delta Green Countdown. It adds the Tradecraft Skill. In and of itself, Tradecraft does little. However, if you want to plant a bug, you must first succeed at a Tradecraft roll and then a Surveillance roll.
If the character makes the Tradecraft roll, but fail the Surveillance, the bug isn't planted.
If the character fails the Tradecraft roll, but makes the Surveillance, the bug is planted. However, it might be easily spotted or in a sub-optimal position to capture conversations in the room.
If both fail, the bug's not planted.
If both succeed, the bug's planted and works as expected.
Does this complicate matters unduly or does it add to the experience? In the above example, would a single Surveillance roll be enough to succeed, in your opinion?
