Back in the day Charactersheets were either a scrap of paper or a third-hand xerox from your DM. The internet came along and soon character sheets were everywhere and they were free for the downloading and printing.
So we now have these character journals. IF you have a character you play constantly then these are just a formated way of what we had done for years; making a sheet and then stapling extra sheest to it.
Character Journals like these are great for the PDF market. Buy it once, print it of dozens of times. You use for the buck here is fantastic.
