simple formula:
huge map, random dungeons, random treasures, throw away the main story, random events (mini stories are fine), events and options change based on your party members ability’s and inventory, age limitations (as your player gets older his skills diminish and eventually death), no ending.. just play for fame and fortune, customizable weapons and armor, multi player (4 party co-op would be nice) and if you have time.. update graphics.. but not top O my list.
