Extra features from the past

All stats not mentioned on the character sheets are average.
If in the game you never used a weapon yet, you can expect to be an average fighter. Or you can get extra points for defining yourself as bad gunmen and be extraordinary by buying points.

The only question is how to stop players from getting lots of points by defining themselves as weak in lots of unnecessary areas. The answer: Only skills from the skill list can be defined as weak.

If you define a skill as being high, you should explain the background for your training. (Actually SotC offers a possibility like this.)
