For the older folks who can remember a game called Dungeon Keeper, this was an underground making of an evil lair type of game.
One of the neat features was being able to take control of a creature and see from the first person view.
Why would that be helpful?
- Fun way to explore the city from a different perspective
- Take control of a footman or archer and take part of the action!
3, Help build, mine, carry stuff, for tasks that you want to micro-manage
- Talk to citizens (like they are NPC)
