What would be interesting is to have places/areas/towns which were not controlled by humans.
Ok youve got the elf place deep in the dark forest and 2 dwarven places but thats it. Everywhere else is human controlled.
Id like to see a real elf area deep in the forest larger than the above were you can get 4-5 quests and an alchemist.
An Orc war camp which doesnt usally allow other non-orc races unless you first talk to the orc gaurd and perform a quest for him. When you suceed you are allowed to enter.
I feel that it would add a variety and a different feel to the game.
Ive got 1-2 plotlines for divnity 2 which I will post in a few days time.
