CT LBB Books 4-7 allowed for 1 skill chance roll per assignment, plus additions for special assignments, promotions etc.
I reckon so. I allow the rule to stand.
I allow the chargen process to complete then let the players reduce their skill lists to further personalise their characters. It adds a little uncertainty and a fair bit of hesitation for players to remove/reduce skills they might possibly need one day
Also available are "wet wear" or implants that combine communicators, computer interface and one non combat skill (level 0) not on the players list. Implants appear at TL9-10.
