Types of maps

In video games their are many types of maps the biggest two are open and controlled.  Open world allows you to move freely around a map and you can do a lot the best example is Elder Scrolls.  I like this type of map because it is always fun to go somewhere different every time.  Controlled maps allows you to see a lot but you can not go to though areas.  Some games do this well like Dragon Age but that is squad type fighting.  Maybe that is something to think about too, most squad type video games have controlled maps and most single player have open.  What do you all think?  How should I think about my maps for this game?  Any input will be welcomed.

Class system concept

Here what I have at the moment for the class system

Fighter
  Monk
  One-handed
  Two-handed
Rouge
  Blade
  Archery
  Traps and nicnaks
Mage
  Element
  Haler
  Cures

This will be expanded in a later post but this is what I am think next will be the prestige classes that people can be in at a particular level.

Fighter
  Paladin
  Order of the Fist
  Battlemaster
  Dulist
Rouge
  Ranger
  Assassin
  Theif
  Fastcaster
Mage
  Order of the Fist
  Wizard
  Fastcaster
  Bard

Well that is what I have hope you all like it and these are subject to change.
