I am hoping for anywhere between four and six party members active on the field, with additional characters tagging along and setting up camp who can be swapped in and out as needed.
As far as actual characters are concerned, I hope for a healthy balance between the conventional, traditional options and the more unusual. The most popular combination for gamers in almost every fantasy game is a male human with a sword. To some that may be boring, though to others it is a key element to enjoyment.
