Would there be a reason why basic abilities (e.g., Endurance, Resistance, Agility, Speed, etc) are not pre-listed on the sheet? (Won't everyone have these? Thus, saving everyone from writing out all these items each time.)
Yes, actually. The core rulebook will have an expanded character sheet, one where all of the abilities are prelisted, just as you say. That sheet has a modular approach, with up to seven seperate sheets, using only those needed, depending on skill sets. However, for the preview, I felt a simple three page layout would convey the feeling of the game better. I didn't want to give the impression of complexity.
We'll provide several different sheets on the main website when that goes live in April...
