I've only just started chapter 2, so maybe I just haven't gotten to it yet, but is it ever explained exactly what different stats ("parameters") do?
Trying to buy equipment and stuff and while I can guess what speed and some of the others do, some are very vague. For example what in the world does stamina do for Mark? I think being able to read the descriptions of these stats from some book or menu would be greatly informative and a big help.
